Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. Having spent its life in orbit between Jupiter and Uranus, this comet was deflected in 1974 by a close encounter with Jupiter and now orbits between Jupiter and Earth. Returning to Earth by parachute in 2006, the cometary dust sample will be analyzed for clues to the formation and primordial composition of our Solar System.
