Lobster Claw Nebula
Sh2-157, also known as the Lobster Claw Nebula, is a bright emission nebula in the constellation Cassiopeia. It lies just south of the better-known Bubble Nebula (NGC 7635). The Lobster Claw Nebula is approximately 11050 light years (3390 parsecs) from the Earth. The predominantly yellow part of the nebula is a very large H II region that is ring-shaped by the stellar wind of several giant stars, including the bright and very young Wolf-Rayed star WR 57. The small bright region at the left and up of center of the image is Lyn's Bright Nebula 537 (LBN537 or Sharpless 157a). The blue colored regions at the right part of the image mainly consist of highly ionized oxygen (OIII) and other gases. The small open star cluster NGC 7510 is located at the bottom right part.
