Comet ISON Approaches Perihelion

Posted by Soulskill on from the put-on-your-game-face dept.

New submitter BugNuker writes "Comet ISON has been speeding towards the sun, and while doing so, it has been getting brighter. There was hope that ISON would be 'Comet of the Century' material. That does not seem to be the case, but it still exists and it's still very interesting. Recently, ISON has undergone some outbursts, making it a near naked-eye object. ISON is still approaching perihelion (it will get there at 18:25 UTC on 28 November). For now, we can keep watching the STEREO spacecraft images for more evidence." Emily Lakdawalla of the Planetary Society put together this animated GIF of the comet from images taken by the STEREO-A spacecraft. Karl Battams put together a fascinating GIF as well. The Planetary Society has a list of information feeds and scheduled events for keeping tabs on ISON.

    It's winter here. The only thing you're likely to see is a hungry bear and a bunch of clouds.

    We don't do tan lines in Alaska. Global warming hasn't quite got that far.
