The Whirlpool Galaxy

The Whirlpool Galaxy

This is Messier 51, the so called Whirlpool Galaxy - an interacting grand-design spiral galaxy with a Seyfert 2 active nucleas, located about 31 million light years from us in the constellation Canes Venatici.

Discovered in October 1773 by Charles Messier, M51 (and its partner NGC 5195) is one of the most-observed and studied interacting galaxies. With an apparent magnitude of 8.4mag it’s relatively bright and easily visible with also smaller amateur telescopes.
