A rare comet is expected to light up the night sky within the next month and the display could be spectacular. It's known as the comet "ISON," and at 108 billion miles away it is just now becoming visible on Earth. Tim Forrest is an avid sky watcher. He has spent years chasing down comets. He says right now ISON is only visible using high definition equipment but in a matter of weeks it should be able to be seen with the naked eye.
"Around Thanksgiving and through the month of December provided it makes it around the sun without destroying itself," says Forrest.
There is still a good amount of uncertainty as to whether the comet will survive long enough to light up the sky at the end of the month. First, it must make a hairpin turn around the sun. If it completes this turn, it will be visible for the end of the year.
At it's best, projections say the comet could be brighter than Halley's Comet, and potentially be best comet seen since the 1600's.
The Comet Ison will make the turn around the sun on November 28th.
