SH2-263, also known as Sharpless 263, is an emission nebula in the constellation Monoceros. It lies about 2,400 light years from Earth. The nebula’s characteristic red colour comes from the presence of ionised hydrogen gas. It is an interesting example of the interactions between young, hot stars and the surrounding interstellar medium.
