A false-colour composite of images taken by the Deep Space 1 spacecraft shows Comet Borrelly's nucleus, dust jets, and coma (its hazy, dusty atmosphere). The nucleus, which appears gray, is about 5 miles (8 kilometres) long. The main jet of dust escaping from the nucleus extends to the bottom left. The comet's nucleus is the brightest part of the image. The other features have been colour coded so that red indicates areas that are about a tenth as bright as the nucleus, blue a hundredth as bright, and purple a thousandth.
