Star of the week: Albireo

Albireo – one star blue and the other golden – as captured by EarthSky community member Tom Wildoner in July, 2015. Visit Tom’s blog, Leisurely Scientist.

Albireo – also called Beta Cygni – isn’t the brightest star in the sky. It looks like an ordinary single star to the eye. But peer at it through a telescope, you’ll learn why stargazers love Albireo. With a telescope, you’ll easily see Albireo as a beautiful double star, with the brighter star gold and the dimmer star blue.

How can you see Albireo as two stars? They are best viewed at 30X (“30 power” or a magnification of 30). Unless you have exceedingly powerful binoculars, mounted on a tripod, binoculars won’t show you Albireo as two stars, but any small telescope will. When you do see Albireo as two stars, notice the striking color contrast between the two.

How can you spot Albireo in the night sky? It’s easy to find, if you can located Cygnus the Swan. Cygnus has an easy-to-recognize shape, that of a cross, and the constellation is also known as the Northern Cross. The brightest star in Cygnus, called Deneb, marks the head of the Cross or the Tail of the Swan. Albireo marks the base of the Cross or the Head of Cygnus.

The Summer Triangle

The constellation Cygnus lies within a larger star pattern known as the Summer Triangle. See the three bright stars here: Vega, Deneb and Altair? See how the pattern of the cross (Cygnus the Swan) likes inside the triangle made by those three stars? More about the Summer Triangle here.

The two stars of Albireo constitute a true binary star system. In other words, its two stars aren’t merely a chance alignment as seen from Earth. Instead, they revolve around a common center of mass.

These two stars lie quite far apart, however, and might take as long as 100,000 years to orbit one another. Even though these two stars appear close together in a telescope, keep in mind that you’re looking at a system that’s 430 light-years away.

By the way, the brighter of the two stars in the Albireo system has been found with advanced telescopic techniques to be two stars as well. Thus there are at least three stars in this system.

With just weeks left for the Great American Eclipse, I decided to shoot the sunrise sequence using my solar filter. During the eclipse, I’ll likewise be focusing on doing a wide-angle and telephoto composite. The foreground was taken before the sunrise to get a silhouette of the Empire State Building in New York City. The remaining solar disc imaging was done using my solar filter.

News digest – making radiotherapy kinder, artificial intelligence, arthritis and… ‘bum gums’?

  • Some breast cancer patients could be spared the side effects of treatment after our study found targeted radiotherapy was just as good at preventing the disease from returning as giving radiotherapy to the whole breast. Reported by The Telegraph and others, the findings from our trial could help improve the quality of life of many women – our press release has the details.
  • The first detailed look into the genetic and molecular characteristics of cancers that have spread could boost research efforts into making treatment more personal. We reported on this new US study.
  • Taking out cancers’ sidekick – healthy cells that have been coerced by the tumour – could be a way to fight many types of the disease in the future, our new study suggests. The early research points towards new ways to target tumours – check out our press release for more info.
  • Using computers to analyse immune cells in tumours could help identify some breast cancer patients who have a high risk of their disease coming back, according to a new study we helped fund. The test still needs putting through its paces in trials, but it could one day help guide treatment decisions and pinpoint those patients who might respond to certain drugs, reports the Independent.

The pounds that the NHS could save per pancreatic cancer patient if their surgery is fast-tracked

  • Time to get a new lab partner? According to the BBC, tech companies have claimed that pairing scientists with artificial intelligence could help drug development and cut costs at the same time. Various pharma companies have now struck deals with AI firms to pursue the idea.
  • Teaching an old drug new tricks: A UK team of scientists has found that an arthritis treatment could help some blood cancer patients. It’s too early to be calling it a breakthrough, but the researchers hope to start testing their idea in people next year.
  • An early trial in Birmingham has found that getting pancreatic cancer patients into the operating theatre sooner – reducing waiting times from 2 months to 2 weeks – boosts the success rate of surgery and cuts NHS costs. Contrary to the Express headline, as the BBC points out, it’s not clear if fast-tracking surgery can help save lives, but for a cancer that’s hard to treat, it’s an encouraging start.
  • Tobacco companies may have been playing dirty, according to the Guardian. The report claims new research suggests some companies have been manipulating their prices to make the habit harder to kick. Check out our website for info on the best ways to stop smoking.

And finally

  • Widely reported news that ‘bum gums’ – a history of gum disease – could increase the risk of several types of cancer in postmenopausal women may have caused alarm this week. But while good oral health is important, the US study had us less than convinced – not least because one of the authors receives funding from Colgate… For reliable ways to reduce your cancer risk visit our website.

See Earth’s shadow and Belt of Venus

In both the evening and morning sky, try watching for Earth’s shadow. Earth’s shadow is a deep blue-grey, darker than the twilight sky. The pink band above the shadow – in the east after sunset, or west before dawn – is called the Belt of Venus.

We show a lovely photo of the Earth’s shadow on the chart at the top of this post (image from Woomera missile range in Australia. Used with permission). The image shows more or less the same moon phase that you’ll see on the night of August 5. It’ll be a waxing gibbous moon that’ll be visible in the east after sunset on this evening.

Meanwhile, Earth’s shadow can be seen any clear evening, ascending in the eastern sky at the same rate that the sun sets below the western horizon.

The shadow of the Earth is big. You might have to turn your head to see the whole thing. And the shadow is curved, in just the same way that the whole Earth is curved. Earth’s shadow extends hundreds of thousands of miles into space, so far that it can touch the moon. Whenever that happens, there’s an eclipse of the moon, like the partial lunar eclipse coming up in the world’s Eastern Hemisphere on the night of August 7-8, 2017.

Partial lunar eclipse on August 7-8

Total eclipse of sun: August 21, 2017

Yes, we have eclipse glasses! Purchase now. Allow one week for U.S. delivery. Sorry, we can no longer guarantee delivery of international orders by August 21.

Bottom line: Check out Earth’s shadow – in the east after sunset or in the west before sunrise – next time you have a clear sky. I often see it while out on the streets of my town as the sun is setting. The pink coloration above the shadow is called the Belt of Venus.

The failed feline spies [Life Lines]

Wow. This is a very interesting bit of history on how the CIA tried to use cats as spies. But as any cat owner knows, cats do not always do what you want them to do when you want them to do it.

An Inconvenient Review [Class M]


ILLUSTRATION:
THE CLIMATE PROJECT

Eleven years ago David Guggenheim and Laurie David managed to turn a documentary about a most unlikely subject — a slide show by a man famous for being too dull to be elected president — into an Oscar-winning international hit. The reaction to An Inconvenient Truth convinced the film’s star to assemble and train an army of climate-crisis presenters now known as The Climate Reality Project.

Guggenheim and David are gone, replaced by a new editorial team, but the star is back with An Inconvenient Sequel: Truth to Power. Most of the reviews so far are less than complimentary, and for good reason. But I’m going to go out on a limb and recommend the film anyway, largely because it’s a more honest portrayal of Al Gore the human being — and his approach to addressing the biggest public policy challenge of our time — than was the 2006 vehicle.

First, though, let’s address the problems with the film, beginning with its raison d’être. It’s really not a sequel at all, more like An Inconvenient Remake. Just as Gore’s Keynote slide show has managed to stay current without actually evolving much over the past decade (not necessarily a bad thing), so the film preserves many key elements, swapping out each pivotal moment for a modern analog, and sticking close to the guiding philosophy of balancing tales of desperation with testimonials of hope.

Gone is the graph in which the trendline of rising greenhouse-gas emissions goes so high that Gore needs a cherry-picker to reach the end point. But the 2017 replacement, a column chart of the annual contributions of new solar power to Chile’s electricity mix, gets effectively the same treatment. Flood videos from 2015 replace flood videos from 2005. And there is still the requisite example of Gore getting all verklempt in front of his trainees as he describes the rising death tolls from extreme weather. So even with a new director and production crew, Gore is firmly in charge of the both the theatrical and cinematic formulas.

There’s nothing inherently wrong with this. But do we really need an updated version of something we’ve already seen? One can argue that, yes, we do. Just as Hollywood seems to have a inexhaustable supply of Spiderman remakes because it knows that there’s always a younger audience who will prefer the latest version, so Gore understands the need to keep it fresh. The scientific underpinnings of the story notwithstanding, this is popular culture we are talking about here.

To be fair, there are significant differences between the two docs. The first one managed to sear certain images into viewers’ brains. The cherry-picker scene or the one where New York City gets inundated by sea-level rise are perfect examples. In fact, despite the emphasis on Gore’s personal odyssey, I submit that what people remember most about AIT is the evidence for the urgency of doing something about global warming, which is, after all, the whole point of the film.

By contrast (I could be wrong here, but all I can do is reflect my own reactions, and those of the folks sitting near me in the cinema), what most viewers will likely take away from AIS is images of Gore himself. Gore the frustrated presidential candidate, Gore the jet-setting volunteer diplomat, Gore the dear leader, Gore the high-stakes interlocutor, Gore the tired crusader. This is more problematic.

The film hadn’t even been officially released and the same old misleading complaints from the science-denial crowd about his Tennessee home’s electrical bills started flooding the far-right echo chambers. Gore is still hated by much of the country, although for no readily explainable reason, as far as I can tell. Putting him even more front and center is probably not the best way to make friends and influence people.

I am sure many will be surprised by the relatively short shrift given to the presenters, who are, after all, a direct consequence of the original film and a big part of Gore’s legacy. Surely a sequel would pay some attention to them. Yet the only presenter who gets any screen time is a Filipino who is still traumatized by the devastation caused by a typhoon that tore through his island. And even here, Gore gets the last word.

Maybe, though, this is exactly the point. Both Gore’s strengths and flaws are laid bare in the film. Sure, we get far more of him than we probably want. There was no need to rehash his reaction to the Supreme Court ruling that handed the presidency to George W. Bush. That was well explored the first time around. Plus, it’s hard to believe that Gore is responsible for the success of the 2015 Paris Agreement, even though the film makes his critical role as a broker in getting India on board a fundament part of the narrative.

But we get the bad with the good. At times Gore looks like he’s seen better days. Some of the shots feature his less-than-trim physique. There’s the embarrassingly brief encounter in Paris with the newly elected Canadian prime minister, Justin Trudeau, who dismisses Gore’s words of appreciation for bringing Canada back from the dark side by humbly quipping that “it was the Canadian people, not me,” before running off to whatever important appointment he was trying to keep. The film even wraps up with a self-righteous declaration of certainty of purpose.

This level of honesty make AIS worth the 98 minutes it asks of your time. We see both the impact one human being can have, and the limits of such power. Gore could have chosen to close with an admission of the latter, something along the lines of “Maybe I’m just titling at windmills (so to speak), but what else can one man do?” But he didn’t. For better or worse, that’s not who he is. And as carefully scripted as this documentary is, it succeeds much better than its predecessor at revealing the personality that has driven so much of the public conversation around climate change.

By the way, I’m one of the thousands Gore has trained to deliver his presentation, a task I still do from time to time. (As I was finishing off this review, in a public library, someone who had seen one of talks a few years ago walked up and asked me if I’d be doing another one thanks to the attention AIS is getting.) Like all my colleagues, I still care more about the message than about the messenger. But why a decade spreading a brilliantly crafted and compelling message has changed so few minds is a vital question, to which no convincing answer has yet been supplied. If nothing else, this new look at Gore and his methods gets us little closer to one.
