NGC 1579, known as the Northern Trifid, is a diffuse collection of emission and reflection nebula. It is about 2100 light years away in the constellation Perseus. The brighter orange II region is atypical in that it's color not due to the usual emission of hydrogen. Instead, it is believed to be the light of a young massive star that emits strongly in hydrogen alpha; it's light is being dimmed by dust within the nebula, yielding isn't orange color.
