Owl nebula, M 97, NGC 3587
The Owl Nebula is a planetary nebula located approximately 2,030 light years away in the constellation Ursa Major. This object is known by the catalogue identifiers Messier Object 97 (M97) and NGC 3587. It was discovered by Frenchastronomer Pierre Méchain on February 16, 1781. When William Parsons, 3rd Earl of Rosse observed the nebula in 1848, his hand-drawn illustration resembled an owl’s head. It has been known as the owl nebula ever since.
