Comet ISON Has Rounded The Sun But Its Fate Remains Unknown

Comet ISON - called by some the "comet of the century" made its way around the sun tonight, but we aren't sure if it survived the trip or not. What happened to the chunk of rock and ice determines how bright it will be in the night sky during December.
