NGC 6357
Emission nebula in the constellation Scorpius / From Wikipedia, the free encyclopedia
NGC 6357 is a diffuse nebula near NGC 6334 in the constellation Scorpius. The nebula contains many proto-stars shielded by dark discs of gas, and young stars wrapped in expanding "cocoons" or expanding gases surrounding these small stars. It is also known as the Lobster Nebula.[4][5] This nebula was given the name War and Peace Nebula by the Midcourse Space Experiment scientists because of its appearance, which, in infrared images the bright, western part resembles a dove, while the eastern part looks like a skull.[6] A petition by anime fans to rename it as the Madokami nebula, due to resemblance with a character, was unsuccessful.[7][8]
