Scientists think that a giant asteroid, which broke up long ago in the main asteroid belt between Mars and Jupiter, eventually made its way to Earth and led to the extinction of the dinosaurs.

With the help of NASA's Spitzer Space Telescope, astronomers have discovered that what was thought to be a large asteroid called Don Quixote is in fact a comet. The left image shows Don Quixote's coma and tail -- features of comets -- as seen in infrared light by Spitzer. The coma appears as a faint glow around the center of the body, caused by dust and gas. The tail, which appears more clearly in the right image, points towards the right-hand side of Don Quixote, into the direction opposite of the sun. The right image represents a more elaborate image processing step, in which the glow of the coma has been removed based on a model comet coma. Bright speckles around Don Quixote are background stars; the horizontal bar covers image artifacts caused by the image processing. Image credit: NASA/JPL-Caltech/DLR/NAU

Comets contain elements such as water, ammonia, methanol and carbon dioxide that could have supplied the raw materials, in which upon impact on early Earth would have yielded an abundant supply of energy to produce amino acids and jump start life.
