NASA unveiled the image on Friday. (MORE: )...

The comet that may put on a spectacular light show during a November date with the Sun, was observed by the Deep Impact mission. The spacecraft has also had close fly-bys of comet's Tempel 1 and Hartley 2 and scientific observations of Garradd. (NASA/JPL-Caltech/UMD (Tony Farnham)) Astronomers are already getting set for the arrival of Comet ISON, which may become one of the brightest comets ever seen when it cruises through the inner solar system this fall. NASA has brought...
