Sun vs. ISON

Tomorrow, Thursday the 28th, as we prepare for Thanksgiving (and Hanukkah) a cosmic drama is set to unfold. For months, astronomers have been observing Comet ISON approach the sun, now estimated to be less than a mile wide, wondering whether the comet will survive its close encounter and re-emerge from behind the sun to become visible to the naked eye through December. You can follow this drama on line. Between 12noon and 2.30 pm (CST) tomorrow, NASA will host a Google Hangout while all eyes on the sun will watch Comet ISON make its plunge, passing perilously close (within 730,000 miles) above the sun’s surface and accelerating to 150,000 mph. Will it survive? Break up? Evaporate? Join the Google hangout to keep track of ISON’s progress!

There is already one recent video posted of ISON coming into view of one of the extended-corona imagers from NASA’s STEREO spacecraft, seen on the STEREO website. Discernible for most of November in binoculars, ISON is probably the most scrutinized comet ever by NASA, but from the beginning of its discovery it’s also been one of the most confusing, frustrating and unpredictable objects to observe over time. I’m still betting on ISON becoming the comet of a lifetime.
