This composite image of the Tycho supernova remnant combines infrared and X-ray observations obtained with NASA's
Spitzer and Chandra space observatories, respectively, and the Calar Alto observatory, Spain. It shows the scene more
than four centuries after the brilliant star explosion witnessed by Tycho Brahe and other astronomers of that era.

The explosion has left a blazing hot cloud of expanding debris (green and yellow). The location of the blast's outer shock
wave can be seen as a blue sphere of ultra-energetic electrons. Newly synthesized dust in the ejected material and heated
pre-existing dust from the area around the supernova radiate at infrared wavelengths of 24 microns (red). Foreground and
background stars in the image are white.
