Comet ISON could put on a spectacular display in late November. Comet ISON could shine brighter than the moon in the night sky. Comet ISON was photographed by NASA’s Deep Impact probe earlier this month.
A NASA spacecraft has captured its first photos of comet ISON, an icy wanderer that some scientists say could dazzle as a "comet of the century" when it swings through the inner solar system later this year.
The photos were taken by NASA’s Deep Impact probe and reveal comet ISON as a bright, dusty ball moving against a star-filled background. The spacecraft snapped the pictures on Jan. 17 and Jan. 18 from a distance of about 493 million miles (793 million kilometers).
Comet ISON has been the focus of much anticipation among scientists and stargazers because of its potential to put on a spectacular display in late November, when it makes its closest approach to the sun. Some forecasts predict the comet could shine brighter than the full moon. As of mid-January, the comet’s tail was more than 40,000 miles (64,400 km).
Will comet ISON sizzle or fizzle?
Some projections state that comet ISON, which is officially designated comet C/20012 S1 (ISON), could shine extremely bright in the nighttime sky, possibly even rivaling the full moon. Whether the comet will meet expectations or fizzle out remains to be seen, but it has already become a target for NASA and amateur astronomers.

Seymour Hersh Alleges Obama Administration Lied on Syria Gas Attack 2013 12 09
