Somewhere, circling a star 63.4 light years from Earth, hides a predator of planetary scale.
NASA and ESA wake up the Rosetta spacecraft for first mission ever to chase down and land on a comet.
It's dead, Jim.
After a run-in with the Sun last night, the "comet of the century" ISON might not have gotten swallowed. At least, not completely.
The "Comet of the Century" has been upgraded from "not a chance" to "possibly."
The Mars Reconnaissance Orbiter checks out the "Comet of the Century," and it's looking like it kinda maybe not be.
100 million miles is a long way to go for a comet viewing party. At least NASA brought a piano.
This little smudge doesn't look like much now, but it's a newly discovered comet that's heading towards the sun. C/2012 S1, as it's known, will make its closest pass in November of next year, by which point astronomers are predicting that it may appear brighter than a full moon. Much brighter.
Just who do those comets think they are, huh? HUH? All cruising around the solar system, leaving their dirty ice trails everywhere. NASA's gonna go in and show them who's boss, and the agency's bringing in the big guns to do it. Literally.
In August of 1883, an astronomer in Mexico named José Bonilla spotted hundreds of fuzzy objects passing in front of the sun that nobody could explain. A new analysis of these observations suggests that what Bonilla saw was anywhere from a billion to a trillion tons of comet passing as close as a few hundred miles from the surface of the Earth.
