M51 - The Whirlpool Galaxy
The magnificent Whirlpool Galaxy (Messier 51), in the constellation of Canes Venatici (The Hunting Dogs). It is without doubt the best and most famous example of a spiral galaxy that is presented face-on to our perspective, and probably only Messier 31, the Andromeda galaxy, is as well-known.
