Astronomers are calling it the “Nasty 1,” but the hefty, rapidly aging star that shines in the center of the image above sure is beautiful. It’s also damn peculiar, and it may hold clues to a stellar mystery that’s puzzled scientists for decades. »
Using NASA’s Wide-field Infrared Survey Explorer (WISE), astronomers have catalogued 20 previously undetected galaxies that are so bright they belong to an entirely new class of objects, including one that releases 10,000 times more energy than the Milky Way — even though it’s smaller. »
Located 1,500 light years away and measuring four light-years across, the gorgeous Medusa Nebula offers a sneak preview of what our Sun will look like when it finally enters into its final death throes.
Using the OSIRIS camera aboard the Rosetta spacecraft, ESA scientists have discovered a strange formation of what appears to be balancing boulders on comet 67P/Churyumov-Gerasimenko.
Twenty years ago, discovering another Earth sounded like a science fictional dream. But within a generation, astronomers now believe we might do just that. »
Dwarf planets, comets, and asteroids are all the rage these days, but we shouldn’t neglect our Solar System’s outer gas planets and their moons. In this new NASA video, 70 days of Neptunian activity was compressed down to 34 seconds — and the effect is pretty damned cool. »
Remember the wonderful Galileoscopes that were developed in 2009 for the International Year of Astronomy? This high-quality, low-cost telescope kit is back for the 2015 International Year of Light (IYL), and new inventory is now available for delivery worldwide. Plus, thanks to generous donations to support science… »
SimEarth was right about one thing. The best way to wet up a planet? Hurl a bunch of icy asteroids at it. »
Stars may be spherical, but that doesn’t mean they explode in a symmetrical and uniform fashion. As a new study shows, stars dramatically writhe and contort before going supernova, blasting their cores in one direction and ejected material in another.
Late last year, astronomers using the ALMA telescope captured an unprecedented image of what appears to be a protoplanetary disc surrounding a young star. Some scientists were skeptical about the claim, but a new simulation run by Canadian astrophysicists is helping bolster its case. »
Starting late Tuesday night and continuing on through early morning Wednesday, debris from Halley’s Comet will light up the sky in this year’s Eta Aquarid meteor shower. Here’s everything you need to know to spot as many meteors as possible.
It may be a terrestrial planet, but the changing atmospheric conditions on the so-called “Diamond Planet” are absolutely nothing like what we experience here on Earth. »
Astronomers watching a small red dwarf star 500 light years away were surprised to notice a brief dip in its already dim light. But they quickly identified the source of the change: the darker mass of a planet passing between the distant star and our vantage point on Earth. »
The International Astronomical Union has designated 20 celestial objects for public naming. The contest, called NameExoWorld, is the first opportunity for the public to give names to numbered stars and their planets. Learn more about the 20 objects here and submit your proposed names. The deadline is June 1, after… »
Aside from having the coolest name for a moon ever, Hyperion is known for its potato-like shape and a surface that looks — and even acts — like a sponge. But as the Cassini spacecraft discovered back in 2005, this Saturnian moon also packs an unexpected punch. »
If you’re ever feeling crappy about not getting recognition for your work, just remember that even Carl Sagan got negs from his scientific colleagues. In fact, he was never allowed into the National Academy of Sciences, despite all he did to popularize the scientific worldview. »
Every now and then, astronomers spy a runaway star, one that’s hurling itself across its galaxy at breakneck speeds. But stars aren’t the only things that occasionally go beserker in the cosmic void: Galaxies themselves will sometimes depart home, never to return. »
