The glowing ring nebula is one of the most impressive astronomical images of the week.

The NGC 1514 Nebula appears like a glowing ring in a photograph taken by an American spacecraft. In fact, this nebula is made up of a white dwarf and a dying star. The matter from the dying star spewed out, creating something like a bubble around both stars. (Photo: NASA).
