Formation of the Southern Crab Nebula (artist's impression)
This artist's impression of the formation of Southern Crab nebula illustrates its hourglass-shared structure, that has been created by the interaction between a pair of stars at its centre: a red giant and a white dwarf. The red giant is shedding its outer layers in the last phase of its life before it too lives out its final years as a white dwarf.
