NASA releases images and video of the comet ISON streaking through the sky towards the sun.
If you've had you fill of Olympics and want something a little more celestial to do this weekend, NASA suggests that you head outside and check out one of the most spectacular meteor showers in years.
International Space Station Commander Dan Burbank was in the right place at the right time yesterday — 239 miles above Earth's horizon in fact — when he spotted Comet Lovejoy putting on a show as it passed Earth back into space.
We've seen comets dive at the sun before, but immediately followed by a huge solar explosion? Not so much. Check out the video below to see how two completely unrelated events created something quite lovely.
Here's a rare close-up of a comet. Hartley 2, to be exact. Named after Malcolm Hartley, the Australian astronomer, "who first identified the body in a photographic plate from a sky survey undertaken in 1986." NASA's Deep Impact probe and Hartley 2 crossed paths about 23 million km from Earth and was only the fifth time a comet has passed so close to a spacecraft.
