Unusual Comet


A spacecraft, Deep Impact, that was used to track and photograph a comet five years ago was awakened from its slumber in order to capture some fascinating shots from about 435 miles away of another comet, Hartley 2, that is approximately 2.9 billion miles away. Not to be confused with Halley's comet, Hartley's is much smaller, only 1.2 miles in length, as opposed to Halley's which is several times larger. The comet, which has a unique bow tie shape, emits jets of ice and dust off of either end, but is remarkably smooth in its central section.
