Tycho's Supernova Remnant: The remains
of a supernova about 7,500 light years from Earth.
Caption: Chandra's image reveals the
turbulent remains of a supernova explosion that was observed by
the Danish astronomer Tycho Brahe in the year 1572. The red,
green, and blue colors represent low, medium and high X-ray
energies, respectively. The image is cut off at the bottom
because of an instrumental artifact. A shock wave produced by
the expanding debris is outlined by the strikingly sharp blue
circular arcs of twenty million degree Celsius gas seen on the
outer rim. The stellar debris, which has a temperature of about
ten million degrees and is visible only in X-rays, shows up as
mottled yellow, green and red fingers of gas.
Scale: Image is 9.6 arcmin on a side.
