Comet Pelted NASA Probe with Bits of Ice During Flyby
This photo from NASA's Deep Impact probe shows part of Comet Hartley 2’s nucleus, with the sun illuminating it from the right. Also visible is a distinct cloud of individual icy particles. The picture was taken on Nov. 4, 2010, the day the spacecraft made its closest approach to the comet.
