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?…

The Chelyabinsk meteor may have snuck up on us by surprise, but it didn't take long for a crack team of astronomers from Colombia to figure out where the damned thing came from and the path it took to get here. By sifting through the copious amounts of video footage available, and after performing some clever…

NASA has released the first video observation of asteroid DA14's record-setting flyby of Earth. 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…

It's been four days since an asteroid tore a hole in the sky over Chelyabinsk, scaring the crap out of the city's inhabitants and pretty much everyone else around the globe. Details are finally starting to emerge about this jaw-dropping incident, so we've prepared a round-up of the preliminary findings.

It wasn't nearly as dramatic as the fireball that exploded over Russia yesterday, but last night the San Francisco Bay Area saw its own light show last night when a meteor streaked across the night sky.

Early this morning, a fireball blazed over the Chelyabinsk region in Russia, shattering windows, collapsing roofs, and injuring hundreds of people. Given that it was one of the biggest meteors to hit Earth in possibly a century, why didn't we see it coming?

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 favorites …

For those who like to start their day with something mindblowing: here's your chance to start today with four.

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.

An absolutely spectacular meteor was witnessed tearing across the California sky last night, reportedly generating a rare sonic boom in the process.
