The Ring Nebula is about 2,000 light-years from Earth and measures roughly 1 light-year across. Located in the constellation Lyra, the nebula is a popular target for amateur astronomers. Previous observations by several telescopes had detected the gaseous material in the ring's central region. But the new view by Hubble's sharp-eyed Wide Field Camera 3 shows the nebula's structure in more detail.
Scorpius also contains several notable deep sky objects. The Butterfly Cluster, or Messier 6 (NGC 6405) is an open cluster of stars that form a shape similar to that of a butterfly. The brightest star in the cluster is BM Scorpii, an orange supergiant, while most of the other bright members are hot, blue B-type stars.
