Owl Nebula M97
The Owl Nebula is also known as Messier Object 97 or NGC 3587. It is a planetary nebula in the constellation Ursa Major. It was discovered by Pierre Mechain in 1781. M97 is regarded as one of the more complex of the planetaries. The 16th magnitude central star has about 0.7 solar masses. This nebula formed roughly 6,000 years ago. The nebula gets it name due to the appearance of eyes like owls.
