As 2013 draws to a close, we once again cast our thoughts to all things astronomical for the coming year.

Incredible Footage Shows a Perseid Meteor Exploding

Personally, I’ve never seen anything like this, and photographer and digital artist Michael K. Chung said he couldn’t believe what he saw when he was processing images he took for a timelapse of the Perseid meteor shower.

What's the difference between a comet, asteroid, meteor, meteoroid and…

With all the recent buzz over asteroid AD14, the meteor over Chelyabinsk, the fragments of meteorite recovered in Russia's Ural mountains, and yesterday's news that the fireball originated from our solar system's asteroid belt, one can't help but wonder: what's the difference between all these -oids, -ors and -ites?… » 2/27/13 12:40pm 2/27/13 12:40pm

The 45-meter-wide space rock sped past last Friday, coming at one point within 17,200 miles of the planet's surface. That may seem like a wide berth (especially in light of the unanticipated arrival of the 17-meter-wide… » 2/20/13 12:54pm 2/20/13 12:54pm

Our favorite photos from this year's Geminid meteor shower

Last night marked the peak of this year's gorgeous Geminid meteor shower, perhaps the most stunning celestial lightshow of 2012. Photographs of last night's fireballs are still rolling in and stargazers can expect to spot intermittent meteors during predawn hours for the next few days, but here are ten of our… » 12/14/12 12:45pm 12/14/12 12:45pm

Remember the fireball that exploded over California last week? A chunk…

The odds of getting beaned by a meteorite are low. Like, really low. (In fact, the odds of being killed by a meteorite are actually higher than your odds of simply being struck by one. Yes, really. See here for more info.) But last week, Novato, California resdient Lisa Webber came pretty close. » 10/22/12 12:30pm 10/22/12 12:30pm
