Nebula - a massive interstellar cloud of dust, hydrogen, helium and other ionized gases.

The aftermath of the death of a massive star is shown in beautiful detail in this composite image of G292.0+1.8. In color is the Chandra X-ray Observatory image - easily the deepest X-ray image ever obtained of this supernova remnant - and in white is optical data from the Digitized Sky Survey. Although considered a "textbook" case of a supernova remnant, the intricate structure shown here reveals a few surprises.
