Comet ISON, RIP
The "comet of the century" is dead.
Comet ISON, once optimistically called the comet of the century, is dead, the victim of a way-too-close brush with the sun. It was barely a year old.
Eh, I hate to get persnickety but it's way older than one year. Maybe not as a comet per se, but certainly as a celestial snowball hanging out in the Oort Cloud. We've only known about it for a year. There are trillions of bits out there that we've never seen and will probably never see.
The comet, which excited astronomers and the media as it zipped within 730,000 miles of the sun on Thanksgiving Day, was pronounced dead at a scientific conference Tuesday. Astronomers who had followed the ice ball mourned the loss of the sky show that once promised to light up during December.
Naval Research Lab astronomer Karl Battams, who headed the observing campaign for the comet, said ISON (EYE'-sahn) was stretched and pulled by the sun's powerful gravity. It was also hit with solar radiation. And the icy snowball just fell apart.
"At this point it seems like there is nothing left," Battams said at the American Geophysical Union conference in San Francisco. "Sorry, everyone, Comet ISON is dead. But its memory will live on."
