EarthSky’s most-viewed video of 2025 was Will Triggs debunking the supposed Great Planetary Alignment of January 25. Social media had been spreading a claim that all the planets would be lined up on one side of the sun and visible in the sky. And Will clearly explained whether that was even possible and what planets you could see in the sky in January. Read on to see more of our top 6 favorite EarthSky videos from 2025.
Top 6 favorite EarthSky videos from 2025
We live in a changing world, where lots of people are now getting their information by watching online videos. And because we are science communicators with a love of Earth and everything related to the night sky, we want to make sure the information people are getting is accurate. But we also want to share our love and excitement for the beauty that is our universe and our place in it. So we post regular videos at our YouTube channel – YouTube.com/@EarthSky – including interviews with scientists, guides with what you can see in the night sky, photos taken by you, our readers, and so much more! Here are 6 of our favorite EarthSky videos from 2025.
Betelgeuse’s new companion, with discoverer Steven Howell
On July 21, 2025, astronomers announced they discovered a companion star in a tight orbit around the beloved red supergiant star Betelgeuse, in the constellation Orion. How did they find it? And what will happen to this companion star when – as predicted – Betelgeuse explodes someday? Astrophysicist Steven Howell, who led the team that discovered the companion, tells all to EarthSky’s Deborah Byrd. Watch in the video above. And read more about the discovery here.
We shouldn’t be able to see this
On March 26, 2025, an international team of astronomers using the Webb space telescope said they identified bright hydrogen emission from a galaxy in an unexpectedly early time in the universe’s history. The surprise finding challenges researchers to explain how this light could have pierced the thick fog of neutral hydrogen that filled space at that time. Watch the video with Will Triggs above for more, and then read the story here.
Secretary birds are expert snake killers
Every week, Cristina Ortiz brings you news and fascinating stories from the animal kingdom. In February, Cristina shared this video of the long-legged and lethal secretary birds, which can stomp a snake to death. In fact, they can deliver blows to snakes faster than the blink of an eye, quite literally! Watch the video about secretary birds above, and read more about them here.
These bizarre dead stars make gold
Powerful flares from magnetars – compact, dead stars with intense magnetic fields – can create heavy elements such as gold and platinum. Scientists think a single flare from magnetar SGR 1806–20 in 2004 produced not only billions of tons of gold, but a huge mass of heavy elements, possibly equal to 1/3 of Earth’s mass. Eruptions like these could account for up to 10% of the universe’s heavy elements. Watch the video above, and read more about magnetars that create gold here.
