The Whirlpool Galaxy

20 RC image A spiral galaxy very similar to our own Milky Way, seen face-on. There are a couple of hundred billion stars here. The dark splotches are dust clouds, and the tiny pink spots are star forming regions, where new stars (and probably solar systems) are born.

The bright object to the left is another galaxy, a small barred spiral captured by M51. Eventually, they will merge, making a single large galaxy (probably very distorted from its present state). Both galaxies are about 35 million lightyears away.
