Whirlpool in the Sky
This object is Messier 51, otherwise known as the Whirpool Galaxy. It is a pair of interacting galaxies that very much resemble their name, a whirlpool. The smaller galaxy is actually behind the larger one, and there is some speculation as to whether they are truly interactive or not. A small number of scientists think they are just in the same line of sight, and not truly interactive.
