Messier 22

NASA: Hubble Stares into the Crammed Center of Messier 22
This image shows the center of the globular cluster Messier 22, also known as M22, as observed by the NASA/ESA Hubble Space Telescope. Globular clusters are spherical collections of densely packed stars, relics of the early years of the Universe, with ages of typically 12 to 13 billion years. This is very old considering that the Universe is only 13.8 billion years old.

Yes, I've been focusing on these clusters lately myself. If there are any other civilizations out here that's where I'd look for them old and densely packed it would be a spectacular sight being on a planet in the heart of one of these systems.

I think what is fun to grasp is that this is simply a section of our Milky Way, and our galaxy is one of perhaps a trillion. There are so many stars trillion upon trillions, there's got to be life out there.
