Tour of Cassiopeia A
Quicktime MPEG Cassiopeia A is the 300-year-old remnant created by the supernova explosion of a massive star. Each Great Observatory image highlights different characteristics of the remnant. Hubble sees the delicate filamentary structure of gases at temperatures about 10,000 degrees Celsius. In the infrared, Spitzer reveals warm dust in the outer shell. Chandra shows much hotter gases glowing in X-rays at about 10 million degrees. This hot gas was created when ejected material from the supernova smashed into surrounding gas and dust at millions of miles per hour. When combined, the data from these telescopes produce a stunning image of this famous object.
