The Hubble Space Telescope has captured the rainbow-hued "fireworks" of
an old supernova whose dying light first reached Earth some 320 years ago, scientists
said on July 3, 2002. The new image shows red, white, blue, pink and green gas streamers
issuing from Cassiopeia A, the remnants of a massive star in the constellation Cassiopeia,
named for an Ethiopian queen. The colors highlight parts of the debris where chemical
elements are glowing. The dark blue fragments, for example, are richest in oxygen;
the red material is rich in sulfur. REUTERS/Handout/Image NASA and Hubble Heritage
