M97 & M108
M97 the Owl Nebula, is a planetary nebula in the constellation of Ursa Major, The Great Bear.
Estimated to be about 8,000 years old it lies just over 2,000 light years away from us. It's given the monicker 'Owl Nebula' because of what looks to be a round face with two big eyes.
M108, also in Ursa Major, is much further away at approximately 46 million light years. This barred spiral galaxy gets the nickname 'Surfboard galaxy'. This edge on galaxy is thought to have a black hole at it's core 24 million times the mass of our Sun.
Both objects were first discovered by the French astronomer Pierre François André Méchain in 1781. Discovering M108 three days after M97.
