The oxygen in supernova remnant E0102-72 is seen here shining brightly with X-rays of a single energy. The Chandra High Energy Transmission Grating/Advanced CCD Imaging Spectrometer creates a distinct image for each of the individual X-ray energies emitted by oxygen, neon and other elements ejected by the explosion.
