NGC 2170

NGC 2170 or Angel Nebula is a dusty reflection nebula and stellar nursery that formed about 6 to 10 million years ago, located at the edge of a giant star-forming molecular cloud Monoceros R2 (Mon R2), some 2,700 light-years away in the constellation of Monoceros.

In fact, NGC 2170 is just the blue nebula below the orange-red nebula in this image.

NGC 2170 is joined by other bluish reflection nebulae, a red emission region, many dark absorption nebulae, and a backdrop of colorful stars.
