Cassiopeia A,composite image. Supernova remnant Cassiopeia A. This glowing high-energy mass of gas and dust has been expanding for 350 years after the star that formed it exploded in a supernova. It is 11,000 light years distant,in the constellation of Cassiopeia. Data from four space telescopes and one ground telescope have been combined here: gamma rays (magenta) from the Fermi Gamma-ray Space Telescope (FGST); X-rays (blue,green) from the Chandra X-ray Observatory (CXO); visible light (yellow) from the Hubble Space Telescope (HST); infrared (red) from the Spitzer Space Telescope (SST); and radio (orange) from the Very Large Array (VLA) in New Mexico,USA.
