The Rosette Nebula is an enormous cloud (over 100 hundred light years wide) of hydrogen gas and dust, about 5,000 light years away in the constellation Monoceros. There are massive, hot stars in the center that are sculpting that opening. The immense radiation from those stars is compressing the gas and dust, causing continuos new star formation.
