BALTIMORE (WJZ)—A comet looping behind the sun could emerge this fall as a once-in-a-lifetime spectacle, or it may not.
Mike Schuh has more on what he calls the intergalactic snowball.
Educators have a different take.
“It’s called Comet ISON,” said Jim O’Leary, Maryland Science Center.
NASA provided an image of ISON. It has a small head and a big tail.
“That tail can get 10?s of millions of miles long, so it’s huge,” O’Leary said.
