Description

The Lobster Claw Nebula, also known as Sharpless 157 (Sh2-157), is an emission nebula in the Cassiopeia constellation, located about 11050 light-years from Earth. A large HII area, which is ring-shaped by the stellar winds of multiple giant stars, including the luminous and relatively young Wolf-Rayed star WR 57, makes up the nebula's primarily yellow portion.
