Cassiopeia A, is a supernova remnant is located about 10,000 light-years away in our own Milky Way galaxy.
This infrared view shows argon gas (green) that was synthesized as it was ejected from the star.
The data for this image was taken by Spitzer's infrared spectrograph, which splits light apart to reveal the fingerprints of molecules and elements. In total, Spitzer collected separate "spectra" at more than 1,700 positions across Cassiopeia A.
