The angel nebula

Image Description and Details : NGC 2170 is a dusty reflection nebula and stellar nursery that formed about 8 million years ago, located at the edge of the giant star-forming molecular cloud Monoceros R2, some 2,700 light-years away. the constellation of Monoceros. The bluish areas are reflection nebulae, so named because they reflect light from nearby hot stars. The red areas are emission nebulae and glow because ultraviolet light from nearby stars excites hydrogen and other gas atoms in the nebula, which then emit their own light in specific colors. What looks a bit like black ink spread across the image are dark nebulae, and are only visible because of the light they block.
