NGC 6357 is a diffuse nebula near NGC 6334 in the constellation Scorpius. This nebula was given the name War and Peace Nebula by the Midcourse Space Experiment scientists because of its appearance. They said that in infrared images the bright, western part resembles a dove, while the eastern part looks like a skull.[3] The nebula contains many proto-stars shielded by dark disks of gas, and young stars wrapped in expanding "cocoons".
Pismis 24
This nebula includes the open cluster Pismis 24, which is home to several massive stars. One of the brightest stars in the cluster, Pismis 24-1, was thought possibly to be the most massive on record, approaching 300 solar masses, until it was discovered to be a binary system with each star exceeding 100 solar masses.[4]
