The Coma Cluster of Galaxies is composed of thousands of galaxies (and billions of stars), just a fraction of which can be seen in this image. It was created in 2006 by the Hubble Space Telescope as part of an initiative to learn how galaxies in rich clusters form and evolve.
It's hard to imagine for life (in one form or another) to not have also occurred somewhere else once you consider the sheer expanse that you are enveloped by when looking at these photos. Although there's a certain level of... despair? when you realize that there is most likely no way for us (or them) to know about each other. Not now, not ever. All of the civilizations that rise and fall here, up until our extinction, will never know about them, and their entire existence (and vice versa).
