Cas A Supernova Remnant

A ring of bright blobs depicts newly created cosmic dust, in the vicinity of a massive star that blew up around AD 1680. This image of the supernova remnant called Cassiopeia A was obtained by ESA's Infrared Space Observatory ISO. It gives astronomers new insight into the processes in which newly-formed chemical elements, released by a stellar explosion, create dust as they cool. These products enrich the clouds of gas and dust between the stars and help to make possible the formation of planets and perhaps living things, in the vicinity of stars as yet unborn.
