Black Knight is an impossibly black exoplanet, a planet closer to its star than Mercury is to ours and blacker than coal. Today, it passes in front of its sun, and you can watch the transit with astronomers using the world’s largest infrared telescope.
Last night, a giant asteroid was supposed to streak by the Earth, close enough for us to catch a glimpse as it zipped by. Except it never showed, and now astronomers say they have no idea just where the 900-foot asteroid has gone.
It's an asteroid the length of three football fields, it's traveling at over 27,000 MPH, and it will be swinging pretty near to our own planet tonight — not close enough to touch (fortunately), but plenty close enough to get an eyeful. You can watch it here!
Do you live in northern Australia? Lucky you — you're one of the few people on Earth who will be able to watch today's solar eclipse in person. For everyone else, your best bet is to watch it unfold online. The total solar eclipse (the last to occur before March 2015) is set to begin today at 15:35 ET (20:35 GMT). Hit…
Tonight, China and the Western United States will be able to see an annular eclipse, the first of its kind since 1994. An annular eclipse is when the moon lines up between Earth and the Sun to create what looks like a ring of fire. It looks awesome. Of course, not all of us live in China or the West Coast, that's why…
There's going to be a 120-minute long, total lunar eclipse today at 2:20 PM EDT and that, of course, is awesome. But what's not so awesome is that it won't be visible to people in North America. Selfish Moon! Good thing we have Google to live stream the whole shebang.
In case you missed it, NASA is bombing the Moon tomorrow morning at 7:31AM Eastern/4:31AM Pacific. Here you have a simulation of the projectile's approach, which will cause a 30-mile high plume. Check out how to watch it here.
If you have nothing to do on Friday, October 9, at 7:31AM Eastern/4:31AM Pacific, reserve that spot for some serious space fireworks. At that time you can see how NASA bombs the Moon from orbit using this huge thing:
Used by astronomers for years, Slooh is an online service that lets people control space telescopes around the world and take images in real time. They've now launched a novice version for you and me.
