Sh2-119 spans 3 degrees in the sky which is six moon diameters. It is an emission nebula where the gas is excited by the uv radiation from nearby stars and re emits light at frequencies(colors) that are unique to the specific gas. It is in mapped color also know as false color in the Hubbel palette where hydrogen gas emission is green in the image, sulfur gas is in red, and oxygen gas is in blue. The bright star in the middle is responsible for exciting the gas creating the emission and its solar wind cleared out the gas creating the center hole in the gas cloud. It is actually 100 light years in size and 2200 light years in distance.
