Mystery solved: why some galaxies appear dustier on one half than the other (Synopsis) [Starts With A Bang]

“He ate and drank the precious Words,
his Spirit grew robust;
He knew no more that he was poor,
nor that his frame was Dust.” -Emily Dickinson

When we look at spiral galaxies, we think of grand arms, star-forming regions and dust lanes lining our perspective. But unlike face-on galaxies, where everything looks the same, galaxies that appear tilted at an angle often appear to have one half far greater in its dust-richness than the other.

This was regarded as a mystery for a long time, but the recent Pan-chromatic Hubble Andromeda Treasury (PHAT) survey confirmed the leading picture: that the dust lanes are confined to a narrow, central region of the disk, and the dusty appearance is an optical illusion. It’s a simple result of perspective, that more of the brighter stars are hidden behind the dust from one side than the other.

The more researchers look for colistin-resistant bacteria, the more they find [The Pump Handle]

Last year, researchers identified a gene that confers resistance to “last-resort” antibiotic colistin. They found it in several E. coli isolates in China, and it didn’t take long for other researchers around the world to find the same gene, mcr-1, in stored samples once they started looking for it. Researchers have now found mcr-1 in isolates from 32 countries.

The US wasn’t among the initial list of countries finding mcr-1, but it didn’t take long for that to change. In May, Walter Reed Army Institute of Research scientists reported finding mcr-1 in E. coli cultured from the urine of a Pennsylvania woman with symptoms of a urinary tract infection. Then in July, researchers from JMI Laboratories reported finding the gene in an E. coli sample collected in May 2015 in New York. So, this gene has already been in the US for more than a year, and could continue to be found in stored US samples as more labs start looking for it.

Also in July, researchers from Belgium published an article in Eurosurveillance reporting their identification of another gene that confers colistin resistance; they dubbed it mcr-2. They studied isolates collected in 2011 and 2012 from calves and piglets with diarrhea. Out of 105 E. coli isolates, they found mcr-1 in 13. They then analyzed a selection of the remaining samples and identified mcr-2; returning to the 92 samples that did not have mcr-1, they found that 12 of them carried mcr-2.

Like mcr-1, mcr-2 has been found on a plasmid, a piece of DNA that can move easily between different bacteria — though mcr-2 might even disseminate more quickly than mcr-1. This plasmid mobility makes it easier for bacteria to acquire resistance to multiple drugs. So far, the isolates with mcr-1 haven’t carried resistance to all other antibiotic classes. But the ease with which mcr-1 can transfer makes it increasingly likely that we’ll see it acquired by bacteria that are already resistant to the first- and second-line antibiotics.

As is often the case, the best explanation of these developments in antimicrobial resistance comes from Maryn McKenna at Germination. She also tacks on this alarming news:

And in a development that medicine has been braced for, Italian researchers say today that they have found yet another variant of the superbug gene, mcr-1.2, in a child hospitalized with leukemia in Florence. That variant, like mcr-1 and the newly named mcr-2, creates resistance to the very last-resort antibiotic colistin.

But what especially rang their alarm bells is that they found the gene in a strain of bacteria, Klebsiella pneumoniae, that was already resistant to the almost-last-resort antibiotic class, carbapenems, and to several other classes as well. Those bacteria are known by the acronym KPC, and since the early 2000s, they have spread through hospitals around the world. So the Italian discovery signals two things that medicine has feared: that MCR has landed in bacteria that are already good at spreading through healthcare, and that it has begun the process of stacking up in bacteria, alongside other resistance DNA, on the way to creating what could be a truly untreatable bug.

Better surveillance is important to continue to learn more about how widespread the problem is. To slow the emergence and spread of antibiotic resistance, though, the most important thing to do is to halt the routine use of antibiotics in livestock production.

July Pieces Of My Mind #3 [Aardvarchaeology]

  • Excavation finished, team scattered. Now for three weeks’ vacation!
  • This Walter Jon Williams story has two Andean pan pipe bands and a Californian figure swimming troupe that all operate as secret intelligence agents.
  • Interesting jetsam around the shores of the island today. The flip-flop was pretty good. But the rifled camera bag was exceptional. It contained only a wallet, a little fabric case and a blister pack for hypertension medication, all empty. But the case is branded for a camera dealer in Busan, South Korea.
  • I like cormorants. In fact, I think it’s more important that cormorants do well in the Baltic than that professional fishermen do. The latter can re-train and do something else. Cormorants can’t. They’re pretty stupid. But I like them.
  • Junior went to Japan yesterday and I’m reading a Japanese spec-fic crime anthology.
  • As of today, I’m the father of two teenagers. Happy birthday, Jrette!
  • I’ve seen the beavers and seals repopulate my area. Now it seems the foxes are coming back too!
  • Junior attains majority today! He’s taken time off from his summer coding job and gone to Japan with his buddy from his mom’s late-90s maternity group. Love you, man!
  • Haha, Junior’s school just kicked me out of the online call-in-sick and check-for-homework system!
  • Awoke with bad toddler withdrawal.

EarthSky’s meteor shower guide for 2016

Taken during the 2015 Perseid meteor shower in August - at Mount Rainier National Park - by Matt Dieterich. He calls the photo 'Skyfall.'

Composed of images taken during the 2015 Perseid shower at Mount Rainier National Park. Matt Dieterich, who composed it, calls it ‘Skyfall.’ It’s not a depiction of what you’ll see at 2016’s Perseid meteor shower. You’ll likely see one, or two, meteors at a time, possibly more if you catch 2016’s predicted outburst.

August 11-12, possible Perseid outburst in 2016

October 7, 2016 Draconids

October 20-21, 2016 Orionids

November 4-5, 2016 South Taurids

Quadrantid meteor in 2016, caught just as the clouds were closing in, by Deb Kestler in Middletown, Rhode Island.

January 4, 2016 before dawn, the Quadrantids

Although the Quadrantids can produce over 100 meteors per hour, the sharp peak of this shower tends to last only a few hours, and doesn’t always come at an opportune time. In other words, you have to be in the right spot on Earth to view this meteor shower in all its splendor. The radiant point is in the part of the sky that used to be considered the constellation Quadrans Muralis the Mural Quadrant. You’ll find this radiant near the famous Big Dipper asterism (chart here), in the north-northeastern sky after midnight and highest up before dawn. Because the radiant is fairly far to the north on the sky’s dome, meteor numbers will be greater at northerly latitudes in the Northern Hemisphere. In 2016, watch in the wee hours – after midnight and before dawn – on January 4. Fortunately, the waning crescent moon shouldn’t too greatly intrude on this predawn shower.

Around the March equinox … fireball season. A fireball is just an especially bright meteor. Northern spring and southern autumn – for a few weeks around the March equinox – is a good time to see one. It’s fireball season — a time of year when bright meteors appear in greater numbers than usual. In fact, in the weeks around the equinox, the appearance rate of fireballs can increase by as much as 30 percent. Why? No one is entirely sure, says NASA. Read more about fireball season.

April 22, 2016 before dawn, the Lyrids
The Lyrid meteor shower – April’s shooting stars – lasts from about April 16 to 25. Unfortunately, in 2016, the full moon almost exactly coincides with the peak of the Lyrid meteor shower. About 10 to 15 meteors per hour can be expected around the shower’s peak on a dark, moonless night. Lyrid meteors tend to be bright and often leave trails, so maybe a meteor or two might overcome the drenching light of the full moon in 2016. The Lyrids are known for uncommon surges that can sometimes bring the rate up to 100 per hour. Those rare outbursts are not easy to predict, but they’re one of the reasons the tantalizing Lyrids are worth checking out. The radiant for this shower is near the bright star Vega in the constellation Lyra (chart here), which rises in the northeast at about 10 p.m. on April evenings. In 2016, the peak morning is April 22, though under the glaring light of the full moon.

Long meteor caught during the peak of the May, 2016 Eta Aquarid meteor shower, by Darla Young.

May 5 and 6, 2016 before dawn, the Eta Aquarids
This meteor shower has a relatively broad maximum – meaning you can watch it the day before and after the predicted peak of May 6. This shower favors the Southern Hemisphere, and is often the Southern hemisphere’s best meteor shower of the year. By good fortune, in 2016, the moon turns new at or near the shower’s peak. The radiant is near the star Eta in the constellation Aquarius the Water Bearer (click here for chart). The radiant comes over the eastern horizon at about 4 a.m. local time; that is the time at all locations across the globe. For that reason, the hour or two before dawn tends to offer the most Eta Aquarid meteors, no matter where you are on Earth. At northerly latitudes – like those in the northern U.S. and Canada, or northern Europe, for example – the meteor numbers are typically lower for this shower. In the southern half of the U.S., 10 to 20 meteors per hour might be visible in a dark sky. Farther south – for example, at latitudes in the Southern Hemisphere – the meteor numbers may increase dramatically, with perhaps two to three times more Eta Aquarid meteors streaking the southern skies. For the most part, the Eta Aquarids are a predawn shower. In 2016, the May 6 new moon will insure dark skies for this year’s production. The most meteors will probably rain down on the mornings of May 5 and 6, in the dark hours before dawn. But watch on May 7 as well! Plus, the broad peak to this shower means that some meteors may fly in the dark hour before dawn for a few days before and after the predicted optimal date.

David S. Brown caught this meteor on July 30, 2014, in southwest Wyoming.

Delta Aquarid in 2014, from David S. Brown in southwest Wyoming.

Late July and early August, 2016, the Delta Aquarids
Like the Eta Aquarids in May, the Delta Aquarid meteor shower in July favors the Southern Hemisphere and tropical latitudes in the Northern Hemisphere. The meteors appear to radiate from near the star Skat or Delta in the constellation Aquarius the Water Bearer. The maximum hourly rate can reach 15-20 meteors in a dark sky. The nominal peak is around July 27-30, but, unlike many meteor showers, the Delta Aquarids lack a very definite peak. Instead, these medium-speed meteors ramble along fairly steadily throughout late July and early August. An hour or two before dawn usually presents the most favorable view of the Delta Aquarids. At the shower’s peak in late July, 2016, the rather faint Delta Aquarid meteors will have to somewhat contend with the light of a waning crescent moon. But the moon turns new in early August, enabling you to view some Delta Aquarids after the peak date.

Scott MacNeill created this wonderful composite image of the Perseid meteor shower in 2013, at Frosty Drew Observatory in Charlestown, Rhode Island. You can see the meteors coming from their radiant point, in the constellation Perseus.

August 11-12, possible Perseid outburst in 2016!
The Perseid meteor shower is perhaps the most beloved meteor shower of the year for the Northern Hemisphere, and the 2016 prediction for an outburst should have many watching this year’s shower on the night of August 11-12. On that night, if the outburst occurs for you, and if the moon is down and the radiant point is high when it occurs, you might see 200 meteors per hour. But also remember, the Perseids build gradually to a peak beginning in early August. So don’t wait. Watch for Perseid meteors on the nights leading up to the shower, too, even as early as early August. Perseid meteors tend to strengthen in number as late night deepens into midnight, and typically produce the most meteors in the wee hours before dawn. They radiate from a point in the constellation Perseus the Hero, but, as with all meteor shower radiant points, you don’t need to know Perseus to watch the shower; instead, the meteors appear in all parts of the sky. They are typically fast and bright meteors. They frequently leave persistent trains. Predicted peak morning in 2016: night of August 11-12. A waxing gibbous moon will be interfering with the show, but it’ll be gone from the sky by the predawn hours. For best results, watch after moonset and before dawn on the mornings of August 11 and 13. Watch all night on August 11-12 (evening of August 11, morning of August 12).

Draconids near Tucson, Arizona in 2013, by our friend Sean Parker Photography.

October 7, 2016, the Draconids
The radiant point for the Draconid meteor shower almost coincides with the head of the constellation Draco the Dragon in the northern sky. That’s why the Draconids are best viewed from the Northern Hemisphere. The Draconid shower is a real oddity, in that the radiant point stands highest in the sky as darkness falls. That means that, unlike many meteor showers, more Draconids are likely to fly in the evening hours than in the morning hours after midnight. This shower is usually a sleeper, producing only a handful of languid meteors per hour in most years. But watch out if the Dragon awakes! In rare instances, fiery Draco has been known to spew forth many hundreds of meteors in a single hour. In 2016, the waxing crescent moon may somewhat intrude on this year’s Draconid shower. Try watching at nightfall and early evening on October 7.

October 21, 2016 before dawn, the Orionids
On a dark, moonless night, the Orionids exhibit a maximum of about 10 to 20 meteors per hour. But, in 2016, the waning gibbous moon will be out during the morning hours before sunrise, when the Orionid meteors fall most abundantly. More meteors tend to fly after midnight, and the Orionids are typically at their best in the wee hours before dawn. These fast-moving meteors occasionally leave persistent trains. They sometimes produce bright fireballs, so watch for them to flame in the sky. If you trace these meteors backward, they seem to come from the Club of the famous constellation Orion the Hunter. You might know Orion’s bright, ruddy star Betelgeuse. The radiant is north of Betelgeuse. The Orionids have a broad and irregular peak that isn’t easy to predict. This year, 2016, presents a less than optimal year for watching the Orionid meteor shower. The best viewing for the Orionids will probably be before dawn on October 22, though in the glare of the waning gibbous moon..

In 2015, the Taurids put on a spectacular display of fireballs, which lasted many days. Photographer Jeff Dai captured this one over Yamdrok Lake in Tibet.

Late night November 4 until dawn November 5, 2016, the South Taurids
The meteoroid streams that feed the South (and North) Taurids are very spread out and diffuse. That means the Taurids are extremely long-lasting (September 25 to November 25) but usually don’t offer more than about 7 meteors per hour. That is true even on the South Taurids’ expected peak night. The Taurids are, however, well known for having a high percentage of fireballs, or exceptionally bright meteors. Plus, the other Taurid shower – the North Taurids – always adds a few more meteors to the mix during the South Taurids’ peak night. In 2016, the waxing crescent moon will set in the evening early, providing dark skies for this year’s South Taurid meteor shower. The South Taurids should produce their greatest number of meteors shortly after midnight on November 5. Remember, it’ll be possible to catch a fireball or two!

Late night November 11 until dawn November 12, 2016, the North Taurids
Like the South Taurids, the North Taurids meteor shower is long-lasting (October 12 – December 2) but modest, and the peak number is forecast at about 7 meteors per hour. The North and South Taurids combine, however, to provide a nice sprinkling of meteors throughout October and November. Typically, you see the maximum numbers at around midnight, when Taurus the Bull is highest in the sky. Taurid meteors tend to be slow-moving, but sometimes very bright. In 2016, the waxing gibbous moon obtrudes on this year’s 2016 North Taurid shower.

November 17, 2016, before dawn, the Leonids
Radiating from the constellation Leo the Lion, the famous Leonid meteor shower has produced some of the greatest meteor storms in history – at least one in living memory, 1966 – with rates as high as thousands of meteors per minute during a span of 15 minutes on the morning of November 17, 1966. Indeed, on that beautiful night in 1966, the meteors did, briefly, fall like rain. Some who witnessed the 1966 Leonid meteor storm said they felt as if they needed to grip the ground, so strong was the impression of Earth plowing along through space, fording the meteoroid stream. The meteors, after all, were all streaming from a single point in the sky – the radiant point – in this case in the constellation Leo the Lion. Leonid meteor storms sometimes recur in cycles of 33 to 34 years, but the Leonids around the turn of the century – while wonderful for many observers – did not match the shower of 1966. And, in most years, the Lion whimpers rather than roars, producing a maximum of perhaps 10-15 meteors per hour on a dark night. Like many meteor showers, the Leonids ordinarily pick up steam after midnight and display the greatest meteor numbers just before dawn. In 2016, the Leonids are expected to fall most abundantly before dawn November 17, though under the bright light of waning gibbous moon.

December 13-14, 2016, mid-evening until dawn, Geminids
Radiating from near the bright stars Castor and Pollux in the constellation Gemini the Twins, the Geminid meteor shower is one of the finest meteors showers visible in either the Northern or the Southern Hemisphere. However, in 2016, the full moon falls on the peak date of the Geminid shower. The meteors are plentiful, rivaling the August Perseids. They are often bold, white and bright. The zenithal hourly rate for the Geminids is up to 120 meteors per hour, after some good displays in recent years. That is the predicted best rate of the shower, which you might see if you’re watching in a dark country sky on the night of the peak, around 2 a.m. local time (the time on your clock no matter where you are on Earth), when the radiant point is highest in the sky. In 2016, the full moon will be out all night long, subduing the usually prolific Geminid meteor shower on the night of December 13-24.

Everything you need to know: Geminid meteor shower

A word about moonlight. In 2016, moonlight will pose no problem for the May Eta Aquarids, and no serious interference with the January Quadrantids, July Delta Aquarids, August Perseids and November South Taurids. There will be moon-free skies for watching the August Perseids for several hours before dawn. On the other hand, the full moon falls on the peak nights of the April Lyrids and December Geminids. Our almanac page provides links for access to the moonrise and moonset times in your sky.

Most important: a dark sky. Here’s the first thing – the main thing – you need to know to become as proficient as the experts at watching meteors. That is, to watch meteors, you need a dark sky. It’s possible to catch a meteor or two or even more from the suburbs. But, to experience a true meteor shower – where you might see several meteor each minute – avoid city lights.

Know your dates and times. You also need to be looking on the right date, at the right time of night. Meteor showers occur over a range of dates, because they stem from Earth’s own movement through space. As we orbit the sun, we cross “meteor streams.” These streams of icy particles in space come from comets moving in orbit around the sun. Comets are fragile icy bodies that litter their orbits with debris. When this cometary debris enters our atmosphere, it vaporizes due to friction with the air. If moonlight or city lights don’t obscure the view, we on Earth see the falling, vaporizing particles as meteors. The Lyrids take place between about April 16 and 25. The peak morning in 2016 should be April 21, but you might catch Lyrid meteors on the nights around that date as well.

Where to go to watch a meteor shower. You can comfortably watch meteors from many places, assuming you have a dark sky: a rural back yard or deck, the hood of your car, the side of a road. State parks and national parks are good bets, but be sure they have a wide open viewing area, like a field; you don’t want to be stuck in the midst of a forest on meteor night. An EarthSky friend and veteran meteor-watcher and astrophotographer Sergio Garcia Rill also offers this specific advice:

… you might want to give it a try but don’t know where to go. Well, in planning my night photoshoots I use a variety of apps and web pages to know how dark the sky is in a certain location, the weather forecast, and how the night sky will look. Here’s the link to Dark Sky Finder. It’s a website that shows the light pollution in and around cities in North America which has been fundamental for finding dark sites to setup shots. Dark Sky finder also has an app for iPhone and iPad which as of this writting is only 99 cents so you might want to look into that as well. For people not in North America, the Blue Marble Navigator might be able to help to see how bright are the lights near you.

The other tool I can suggest is the Clear Sky Chart. I’ve learned the hard way that, now matter how perfectly dark the sky is at your location, it won’t matter if there’s a layer of clouds between you an the stars. This page is a little hard to read, but it shows a time chart, with each column being an hour, and each row being one of the conditions like cloud coverage and darkness. Alternatively, you could try to see the regular weather forecast at the weather channel or your favorite weather app.

What to bring with you. You don’t need special equipment to watch a meteor shower. If you want to bring along equipment to make yourself more comfortable, consider a blanket or reclining lawn chair, a thermos with a hot drink, binoculars for gazing at the stars. Be sure to dress warmly enough, even in spring or summer, especially in the hours before dawn. Binoculars are fun to have, too. You won’t need them for watching the meteor shower, but, especially if you have a dark sky, you might not be able to resist pointing them at the starry sky.

Are the predictions reliable? Although astronomers have tried to publish exact predictions in recent years, meteor showers remain notoriously unpredictable. Your best bet is to go outside at the times we suggest, and plan to spend at least an hour, if not a whole night, reclining comfortably while looking up at the sky. Also remember that meteor showers typically don’t just happen on one night. They span a range of dates. So the morning before or after a shower’s peak might be good, too.

Remember … meteor showers are like fishing. You go, you enjoy nature … and sometimes you catch something.

Peak dates are derived from data published in the Observer’s Handbook by the Royal Astronomical Society of Canada and Guy Ottewell’s Astronomical Calendar.

This Geminid meteor is seen coming straight from its radiant point, which is near the two brightest stars in Gemini, Castor and Pollux. Photo taken on the night of December 12-13, 2012 by EarthSky Facebook friend Mike O’Neal in Oklahoma. He said the 2012 Geminid meteor shower was one of the best meteor shows he’s ever seen.

Bottom line: 2016 will be a great year for watching meteors in late July and early August. A dark sky is best … peak time is late night to dawn.

Quadrantid meteor in 2016, caught just as the clouds were closing in, by Deb Kestler in Middletown, Rhode Island.

January 4, 2016 before dawn, the Quadrantids

Although the Quadrantids can produce over 100 meteors per hour, the sharp peak of this shower tends to last only a few hours, and doesn’t always come at an opportune time. In other words, you have to be in the right spot on Earth to view this meteor shower in all its splendor. The radiant point is in the part of the sky that used to be considered the constellation Quadrans Muralis the Mural Quadrant. You’ll find this radiant near the famous Big Dipper asterism (chart here), in the north-northeastern sky after midnight and highest up before dawn. Because the radiant is fairly far to the north on the sky’s dome, meteor numbers will be greater at northerly latitudes in the Northern Hemisphere. In 2016, watch in the wee hours – after midnight and before dawn – on January 4. Fortunately, the waning crescent moon shouldn’t too greatly intrude on this predawn shower.

Around the March equinox … fireball season. A fireball is just an especially bright meteor. Northern spring and southern autumn – for a few weeks around the March equinox – is a good time to see one. It’s fireball season — a time of year when bright meteors appear in greater numbers than usual. In fact, in the weeks around the equinox, the appearance rate of fireballs can increase by as much as 30 percent. Why? No one is entirely sure, says NASA. Read more about fireball season.

April 22, 2016 before dawn, the Lyrids
The Lyrid meteor shower – April’s shooting stars – lasts from about April 16 to 25. Unfortunately, in 2016, the full moon almost exactly coincides with the peak of the Lyrid meteor shower. About 10 to 15 meteors per hour can be expected around the shower’s peak on a dark, moonless night. Lyrid meteors tend to be bright and often leave trails, so maybe a meteor or two might overcome the drenching light of the full moon in 2016. The Lyrids are known for uncommon surges that can sometimes bring the rate up to 100 per hour. Those rare outbursts are not easy to predict, but they’re one of the reasons the tantalizing Lyrids are worth checking out. The radiant for this shower is near the bright star Vega in the constellation Lyra (chart here), which rises in the northeast at about 10 p.m. on April evenings. In 2016, the peak morning is April 22, though under the glaring light of the full moon.

Long meteor caught during the peak of the May, 2016 Eta Aquarid meteor shower, by Darla Young.

May 5 and 6, 2016 before dawn, the Eta Aquarids
This meteor shower has a relatively broad maximum – meaning you can watch it the day before and after the predicted peak of May 6. This shower favors the Southern Hemisphere, and is often the Southern hemisphere’s best meteor shower of the year. By good fortune, in 2016, the moon turns new at or near the shower’s peak. The radiant is near the star Eta in the constellation Aquarius the Water Bearer (click here for chart). The radiant comes over the eastern horizon at about 4 a.m. local time; that is the time at all locations across the globe. For that reason, the hour or two before dawn tends to offer the most Eta Aquarid meteors, no matter where you are on Earth. At northerly latitudes – like those in the northern U.S. and Canada, or northern Europe, for example – the meteor numbers are typically lower for this shower. In the southern half of the U.S., 10 to 20 meteors per hour might be visible in a dark sky. Farther south – for example, at latitudes in the Southern Hemisphere – the meteor numbers may increase dramatically, with perhaps two to three times more Eta Aquarid meteors streaking the southern skies. For the most part, the Eta Aquarids are a predawn shower. In 2016, the May 6 new moon will insure dark skies for this year’s production. The most meteors will probably rain down on the mornings of May 5 and 6, in the dark hours before dawn. But watch on May 7 as well! Plus, the broad peak to this shower means that some meteors may fly in the dark hour before dawn for a few days before and after the predicted optimal date.

Delta Aquarid in 2014, from David S. Brown in southwest Wyoming.

Late July and early August, 2016, the Delta Aquarids
Like the Eta Aquarids in May, the Delta Aquarid meteor shower in July favors the Southern Hemisphere and tropical latitudes in the Northern Hemisphere. The meteors appear to radiate from near the star Skat or Delta in the constellation Aquarius the Water Bearer. The maximum hourly rate can reach 15-20 meteors in a dark sky. The nominal peak is around July 27-30, but, unlike many meteor showers, the Delta Aquarids lack a very definite peak. Instead, these medium-speed meteors ramble along fairly steadily throughout late July and early August. An hour or two before dawn usually presents the most favorable view of the Delta Aquarids. At the shower’s peak in late July, 2016, the rather faint Delta Aquarid meteors will have to somewhat contend with the light of a waning crescent moon. But the moon turns new in early August, enabling you to view some Delta Aquarids after the peak date.

August 11-12, possible Perseid outburst in 2016!
The Perseid meteor shower is perhaps the most beloved meteor shower of the year for the Northern Hemisphere, and the 2016 prediction for an outburst should have many watching this year’s shower on the night of August 11-12. On that night, if the outburst occurs for you, and if the moon is down and the radiant point is high when it occurs, you might see 200 meteors per hour. But also remember, the Perseids build gradually to a peak beginning in early August. So don’t wait. Watch for Perseid meteors on the nights leading up to the shower, too, even as early as early August. Perseid meteors tend to strengthen in number as late night deepens into midnight, and typically produce the most meteors in the wee hours before dawn. They radiate from a point in the constellation Perseus the Hero, but, as with all meteor shower radiant points, you don’t need to know Perseus to watch the shower; instead, the meteors appear in all parts of the sky. They are typically fast and bright meteors. They frequently leave persistent trains. Predicted peak morning in 2016: night of August 11-12. A waxing gibbous moon will be interfering with the show, but it’ll be gone from the sky by the predawn hours. For best results, watch after moonset and before dawn on the mornings of August 11 and 13. Watch all night on August 11-12 (evening of August 11, morning of August 12).

Draconids near Tucson, Arizona in 2013, by our friend Sean Parker Photography.

October 7, 2016, the Draconids
The radiant point for the Draconid meteor shower almost coincides with the head of the constellation Draco the Dragon in the northern sky. That’s why the Draconids are best viewed from the Northern Hemisphere. The Draconid shower is a real oddity, in that the radiant point stands highest in the sky as darkness falls. That means that, unlike many meteor showers, more Draconids are likely to fly in the evening hours than in the morning hours after midnight. This shower is usually a sleeper, producing only a handful of languid meteors per hour in most years. But watch out if the Dragon awakes! In rare instances, fiery Draco has been known to spew forth many hundreds of meteors in a single hour. In 2016, the waxing crescent moon may somewhat intrude on this year’s Draconid shower. Try watching at nightfall and early evening on October 7.

Orionid meteor, with aurora, in 2013 by Tommy Eliassen Photography in Norway.

October 21, 2016 before dawn, the Orionids
On a dark, moonless night, the Orionids exhibit a maximum of about 10 to 20 meteors per hour. But, in 2016, the waning gibbous moon will be out during the morning hours before sunrise, when the Orionid meteors fall most abundantly. More meteors tend to fly after midnight, and the Orionids are typically at their best in the wee hours before dawn. These fast-moving meteors occasionally leave persistent trains. They sometimes produce bright fireballs, so watch for them to flame in the sky. If you trace these meteors backward, they seem to come from the Club of the famous constellation Orion the Hunter. You might know Orion’s bright, ruddy star Betelgeuse. The radiant is north of Betelgeuse. The Orionids have a broad and irregular peak that isn’t easy to predict. This year, 2016, presents a less than optimal year for watching the Orionid meteor shower. The best viewing for the Orionids will probably be before dawn on October 22, though in the glare of the waning gibbous moon..

In 2015, the Taurids put on a spectacular display of fireballs, which lasted many days. Photographer Jeff Dai captured this one over Yamdrok Lake in Tibet.

Late night November 4 until dawn November 5, 2016, the South Taurids
The meteoroid streams that feed the South (and North) Taurids are very spread out and diffuse. That means the Taurids are extremely long-lasting (September 25 to November 25) but usually don’t offer more than about 7 meteors per hour. That is true even on the South Taurids’ expected peak night. The Taurids are, however, well known for having a high percentage of fireballs, or exceptionally bright meteors. Plus, the other Taurid shower – the North Taurids – always adds a few more meteors to the mix during the South Taurids’ peak night. In 2016, the waxing crescent moon will set in the evening early, providing dark skies for this year’s South Taurid meteor shower. The South Taurids should produce their greatest number of meteors shortly after midnight on November 5. Remember, it’ll be possible to catch a fireball or two!

Late night November 11 until dawn November 12, 2016, the North Taurids
Like the South Taurids, the North Taurids meteor shower is long-lasting (October 12 – December 2) but modest, and the peak number is forecast at about 7 meteors per hour. The North and South Taurids combine, however, to provide a nice sprinkling of meteors throughout October and November. Typically, you see the maximum numbers at around midnight, when Taurus the Bull is highest in the sky. Taurid meteors tend to be slow-moving, but sometimes very bright. In 2016, the waxing gibbous moon obtrudes on this year’s 2016 North Taurid shower.

November 17, 2016, before dawn, the Leonids
Radiating from the constellation Leo the Lion, the famous Leonid meteor shower has produced some of the greatest meteor storms in history – at least one in living memory, 1966 – with rates as high as thousands of meteors per minute during a span of 15 minutes on the morning of November 17, 1966. Indeed, on that beautiful night in 1966, the meteors did, briefly, fall like rain. Some who witnessed the 1966 Leonid meteor storm said they felt as if they needed to grip the ground, so strong was the impression of Earth plowing along through space, fording the meteoroid stream. The meteors, after all, were all streaming from a single point in the sky – the radiant point – in this case in the constellation Leo the Lion. Leonid meteor storms sometimes recur in cycles of 33 to 34 years, but the Leonids around the turn of the century – while wonderful for many observers – did not match the shower of 1966. And, in most years, the Lion whimpers rather than roars, producing a maximum of perhaps 10-15 meteors per hour on a dark night. Like many meteor showers, the Leonids ordinarily pick up steam after midnight and display the greatest meteor numbers just before dawn. In 2016, the Leonids are expected to fall most abundantly before dawn November 17, though under the bright light of waning gibbous moon.

December 13-14, 2016, mid-evening until dawn, Geminids
Radiating from near the bright stars Castor and Pollux in the constellation Gemini the Twins, the Geminid meteor shower is one of the finest meteors showers visible in either the Northern or the Southern Hemisphere. However, in 2016, the full moon falls on the peak date of the Geminid shower. The meteors are plentiful, rivaling the August Perseids. They are often bold, white and bright. The zenithal hourly rate for the Geminids is up to 120 meteors per hour, after some good displays in recent years. That is the predicted best rate of the shower, which you might see if you’re watching in a dark country sky on the night of the peak, around 2 a.m. local time (the time on your clock no matter where you are on Earth), when the radiant point is highest in the sky. In 2016, the full moon will be out all night long, subduing the usually prolific Geminid meteor shower on the night of December 13-24.

Everything you need to know: Geminid meteor shower

A word about moonlight. In 2016, moonlight will pose no problem for the May Eta Aquarids, and no serious interference with the January Quadrantids, July Delta Aquarids, August Perseids and November South Taurids. There will be moon-free skies for watching the August Perseids for several hours before dawn. On the other hand, the full moon falls on the peak nights of the April Lyrids and December Geminids. Our almanac page provides links for access to the moonrise and moonset times in your sky.

Most important: a dark sky. Here’s the first thing – the main thing – you need to know to become as proficient as the experts at watching meteors. That is, to watch meteors, you need a dark sky. It’s possible to catch a meteor or two or even more from the suburbs. But, to experience a true meteor shower – where you might see several meteor each minute – avoid city lights.

Know your dates and times. You also need to be looking on the right date, at the right time of night. Meteor showers occur over a range of dates, because they stem from Earth’s own movement through space. As we orbit the sun, we cross “meteor streams.” These streams of icy particles in space come from comets moving in orbit around the sun.

Tonight, explore the Big Dipper

Perseid meteor shower outburst ahead! See EarthSky’s meteor shower guide for 2016

Tonight, notice the two outer stars in the bowl of the Big Dipper – Dubhe and Merak. They always point to Polaris, the North Star. To find the Dipper at this time of year, look toward the northwest in the evening. Once you’ve found it – after locating Polaris – look more carefully at the second star from the end of the Big Dipper’s handle. If your sky is dark enough, and your eyesight is good, you’ll see that this star, Mizar, has a nearby companion, called Alcor.

Arabian stargazers referred to Mizar and Alcor as the “horse and rider.” These stars are a good test of the night’s viewing conditions: if you can’t see Alcor, there might be thin clouds up there.

These two stars are what’s called “naked-eye double star,” appearing double from our earthly vantage point. But do they orbit each other? Astronomers aren’t sure. The distances to these stars (as to most stars) aren’t precisely known. If Mizar and Alcor make up a true binary star, it’s a very wide one. If they do lie at the same distance from Earth, their separation is 0.27 light-years … that’s in contrast to eight light-minutes for Earth’s distance from our sun … or several light-hours for the distance to our sun of the most distant worlds in our solar system. Still, it’s possible that Mizar and Alcor could be this far apart and still be orbiting one another, with a very long orbital period of three-quarters of a million years.

Big and Little Dippers: Noticeable in northern sky

Mizar and Alcor, famous double star, are really six stars

Jill Stein and left wing antivaccine dog whistles [Respectful Insolence]

During the political battle last year over the recently implemented California law SB 277, which eliminates nonmedical exemptions to school vaccine mandates and then later during the campaign for the Republican nomination for President, I used a term regarding antivaccine views. That term was “antivaccine dog whistle.” In politics, as you probably now, a “dog whistle” is a term for coded messages that sound like advocating principles with broad acceptance but to a certain subgroup are recognized as code for something else. The analogy is obvious. Just as humans can’t hear much of a dog whistle while the intended recipient (dogs) can, political dog whistles come through loud and clear to their intended audience while those not familiar with the issues hear nothing or something unobjectionable. Thus “states’ rights” became a euphemism for continued discrimination and resistance to federal civil rights mandates. In the case of vaccines, there are “dog whistles” too. For example, whenever you hear a politician discussing in the context of vaccines parental rights health freedom, or fascism (likening school vaccine mandates to an assault on freedom), there’s a good chance that it’s an antivaccine dog whistle. Pediatricians do it too. (I’m talking to you, Dr. Bob Sears!) The purpose of dog whistles in politics is to tell a group with an odious set of beliefs, “I’m with you” without explicitly saying so while couching the message in ideas that many people would consider admirable.

Last year, contrary to the usual stereotype of crunchy lefties being antivaccine, it was mostly conservatives blowing the antivaccine dog whistle. Indeed, Republicans as varied as Chris Christie, Rand Paul, Ben Carson, and, of course, Donald Trump blew really hard on that dog whistle. Over the weekend, though, I learned that Republicans aren’t the only ones good at blowing antivaccine dog whistles. On Friday, Green Party nominee for President, Dr. Jill Stein, found herself in a spot of political bother due to her remarks on vaccines.

Dr. Stein’s problems began when she participated in a Reddit “Ask Me Anything” session a while back. She was asked, “What is your campaign’s official stance on vaccines and homeopathic medicine?” In response, she laid down a screeching series of antivaccine dog whistles:

I don’t know if we have an “official” stance, but I can tell you my personal stance at this point. According to the most recent review of vaccination policies across the globe, mandatory vaccination that doesn’t allow for medical exemptions is practically unheard of. In most countries, people trust their regulatory agencies and have very high rates of vaccination through voluntary programs. In the US, however, regulatory agencies are routinely packed with corporate lobbyists and CEOs. So the foxes are guarding the chicken coop as usual in the US. So who wouldn’t be skeptical? I think dropping vaccinations rates that can and must be fixed in order to get at the vaccination issue: the widespread distrust of the medical-indsutrial complex.

Vaccines in general have made a huge contribution to public health. Reducing or eliminating devastating diseases like small pox and polio. In Canada, where I happen to have some numbers, hundreds of annual death from measles and whooping cough were eliminated after vaccines were introduced. Still, vaccines should be treated like any medical procedure–each one needs to be tested and regulated by parties that do not have a financial interest in them. In an age when industry lobbyists and CEOs are routinely appointed to key regulatory positions through the notorious revolving door, its no wonder many Americans don’t trust the FDA to be an unbiased source of sound advice. A Monsanto lobbyists and CEO like Michael Taylor, former high-ranking DEA official, should not decide what food is safe for you to eat. Same goes for vaccines and pharmaceuticals. We need to take the corporate influence out of government so people will trust our health authorities, and the rest of the government for that matter. End the revolving door. Appoint qualified professionals without a financial interest in the product being regulated. Create public funding of elections to stop the buying of elections by corporations and the super-rich.

Regular readers will recognize this as the gambit I like to call, “I’m not ‘antivaccine.’ I’m pro-safe vaccine and don’t trust the FDA and big pharma.” I will grant that Dr. Stein was a little more—shall we say?—emphatic in her concession that vaccines do good than the average antivaccinationist making these arguments. One almost has to wonder if the lady doth protest too much. However, the rest of her word salad above could be cribbed from any number of antivaccine websites. Hell, even Andrew Wakefield concedes that vaccines do good and claims not to be “antivaccine.” Then he routinely launches into the same sort of rant that Dr. Stein engaged in above.

Dr. Stein is also sadly mistaken about a great many things. For example, her rant about “corporate influence” on the vaccine approval process is straight out of the antivaccine playbook and based on incorrect information. As David Weigel pointed out, the most members of the Vaccines and Related Biological Products Advisory Committee work at academic or medical institutions, not drug companies. Yes, there are representatives from drug companies there, but they are a minority. Similarly, the linking of “Monsanto lobbyists” to vaccine regulatory approval is yet another page straight out of the antivaccine playbook. None of this stopped Dr. Stein from doubling down when she sat with the Washington Post’s Sarah Parnass and Alice Li:

“I think there’s no question that vaccines have been absolutely critical in ridding us of the scourge of many diseases — smallpox, polio, etc. So vaccines are an invaluable medication,” Stein said. “Like any medication, they also should be — what shall we say? — approved by a regulatory board that people can trust. And I think right now, that is the problem. That people do not trust a Food and Drug Administration, or even the CDC for that matter, where corporate influence and the pharmaceutical industry has a lot of influence.”

Of course, the CDC doesn’t decide which vaccines are approved. The FDA does. The CDC only chooses vaccines that are already approved to place on its recommended vaccine schedule. As for Dr. Stein’s claim that most countries rely on voluntary vaccination and the trust of their citizens in their government, that’s a very simplistic version of events. In fact, various countries use a variety of means of persuasion, mandates, and, even in some cases compulsion, to assure high vaccination rates. Australia, for instance, offers financial incentives and recently implemented a “no jab no pay” policy that denies welfare payments to children who don’t vaccinate. As for voluntary programs maintaining a high rate of vaccination, well, the UK learned in the wake of Andrew Wakefield’s MMR scare, that doesn’t always work so well.

In addition, Dr. Stein seems not to be up on the latest vaccine data:

As a medical doctor, there was a time where I looked very closely at those issues, and not all those issues were completely resolved.

There were concerns among physicians about what the vaccination schedule meant, the toxic substances like mercury which used to be rampant in vaccines. There were real questions that needed to be addressed. I think some of them at least have been addressed. I don’t know if all of them have been addressed.

The issue of mercury in vaccines in the form of the preservative thimerosal was resolved nearly 15 years ago. Thimerosal was removed from childhood vaccines. Moreover, there was never any compelling evidence that thimerosal-containing vaccines had anything to do with autism. It’s something I’ve written about tiem and time again, and I know. As for these “real questions that needed to be addressed,” one notes that these issues have been addressed ad nauseam. Over and over and over again. In every case, in the case of every well-designed study looking at the issue, no epidemiological link between vaccines and autism or vaccines and the diseases antivaccinationists attribute to them has been found. I’ve blogged about this very issue more times than I can remember. I’ve blogged more studies than I can remember. This is not controversial. Vaccines are safe and effective. Just because Dr. Stein is too clueless to realize this doesn’t make these “concerns” scientifically valid.

In the face of criticism, Dr. Stein tried to defend herself when asked what she says to people who think she’s antivaccine:

Her response:

What I say to those people is that we need regulatory agencies we can trust. I’m definitely not anti-vax; what I have raised is the issue that we need an FDA that’s working for us, that’s not working for the pharmaceutical industry. I think that makes some people uncomfortable, so they’re trying to smear me as being anti-vaxxer. I’m not anti-vax; I’m just saying we need good, reliable data so that the American people know what we’re doing. I mean, it’s like saying the FDA, that has leadership from Monsanto, should tell us what kind of food is safe? No, you get Monsanto out of there, you get the pharmaceutical companies out of there, and then we can trust…

In other words, she basically just doubled down on the same antivaccine dog whistles. The only difference between her and Rand Paul or Chris Christie is that Republicans couch their antivaccine dog whistles in appeals to freedom and parental rights while Dr. Stein couches hers in distrust of big pharma. Either way, the message is the same to antivaccinationists: “I’m with you,” or, at least, “I sympathize with your views.” As I said in other places, if you keep mentioning big pharma and the FDA and how much you distrust them in the context of a discussion about vaccines, you’re blowing antivaccine dog whistles.

Not surprisingly, Dr. Stein’s admirers leapt to her defense with scientifically ignorant assertions that she’s not antivaccine because she says she’s not antivaccine. For example, Dan Arel tried to argue that, sorry Clinton supporters, but Jill Stein is not the antivaccine presidential candidate, but even he was forced to admit that her statements were “straight anti-vaxx pandering,” adding:

While I still feel okay saying Stein is not “anti-vaccine” I cannot confidently say she is not anti-science and that she does not overly pander to the anti-science and anti-vaccine crowd.

A leader needs to stand up against the movement that is killing children, not court their vote.

Unfortunately, a usually trusted source, a source that I’ve admired and cited for years, fell hook, line, and sinker for Dr. Stein’s defense, based on her statements and a statement from Dr. Stein’s campaign denying she is antivaccine and a Tweet:

I expressed my disappointment on Twitter, and Kim LaCapria responded:

And:

I actually agree that it isn’t black and white. Here’s the problem. By declaring the criticisms of Dr. Stein as antivaccine as unequivocally false, Snopes made it black and white. The very best spin one can put on Dr. Stein’s statements is that she is pandering to antivaccine activists. That’s the very best spin. The worst spin is that she is antivaccine. Thus, it’s not editorializing to conclude that the contention that Jill Stein is antivaccine is at least partially true, because that’s what the evidence is most consistent with. She’s parroted antivaccine talking points. There is no denying that.

Then on Twitter there was this:

This one really annoyed me because I wrote about what Hillary Clinton and Barack Obama said about vaccines and autism, back when they said it in April 2008 during the Democratic primary campaign, and actually what Obama and Clinton said back then wasn’t worse than what Jill Stein said. They basically both did some vacuous politician-speak promising more research into environmental causes of autism. As I said at the time, “calling for more research” is the cop-out that all politicians use whenever there’s an issue that is contentious, but that wasn’t not why the Democratic candidates received a dose of Orac’s loving attention. Rather it was because in answering these questions the way they did, they both fell for the very frame that antivaccinationists wanted them to fall for with respect to vaccines and autism. What they didn’t do is to rant about how the FDA and CDC are in bed with big pharma and cast doubt on the safety and efficacy of vaccines the way that Jill Stein did. More importantly, neither of them are physicians, and neither of them ever repeated the same nonsense. They figured out their mistakes and didn’t make them again. Indeed, Hillary Clinton made a point of Tweeting:

And in her acceptance speech at the Democratic National Committee, Hillary Clinton also made it a point of stating, “I believe in science.” I could quibble that you don’t need to “believe” in science for it to work and be valid, but it’s refreshing to hear a candidate say that, and, yes, I know that Hillary Clinton’s record isn’t perfect on that score, given her admiration for Mark Hyman and his functional medicine.

So the question remains: Is Jill Stein antivaccine? To be honest, I’m not sure whether she is or not. It almost doesn’t matter. Almost. Certainly, at the very least she is aware that what she is saying sounds antivaccine. It’s like racism. Whenever you hear someone say, “I’m not a racist, but…” you know that whatever follows after the “but…” is almost certainly going to be racist as hell. It’s the same with antivaccine views. If someone feels obligated to say, “I’m not antivaccine, but…” you know that whatever follows is highly likely to be antivaccine as hell. Jill Stein fits that pattern. However, I rather suspect that she probably isn’t really antivaccine. She does, however, clearly feel the need to pander to the antivaccine fringe, which is sad. She’s also dodged the question in so many ways. She’s been asked if vaccines cause autism, and in response she initially said that there wasn’t. But then she changed her mind, deleting her original Tweet and substituting another one. Here’s the one that’s there now:

And here’s what someone noticed:

That is pandering to the antivaccine movement. It’s more subtle than her earlier pandering, but it’s pandering nonetheless.

Think of it this way. I’ve written many times about how antivaccine Donald Trump is. Indeed, he’s been spewing antivaccine nonsense since at least 2007, long before ever running for President. Indeed, given how much Donald Trump lies and how often he switches positions, what is amazing about his antivaccine beliefs is how long he’s expressed them and how consistent he’s been in expressing them. He really appears to believe them. In a way, that makes Jill Stein arguably worse than Donald Trump in that she probably doesn’t believe the antivaccine BS she’s been laying down, but she lays it down anyway. In other words, she chooses to pander to antivaccine loons with antivaccine dog whistles for left wingers.

And, as Skeptical Raptor tells us, vaccines aren’t the only topic where Jill Stein gets the science wrong.
