In this image NGC 6888: The Crescent Nebula. It is an emission nebula, which can resemble a human brain, which is about 4700 light years from our solar system and can be identified in the constellation Cygnus. The name derives from its "hump" which appears to the west as the Moon observable in the waxing phase. It owes its shape (bubble) and brightness to the stellar wind generated by the Wolf-Rayet star which is inside it.
