Globular clusters worth a look

Scientists theorise that any extraterrestrial civilisation that developed in a globular cluster — a region of space with thousands to millions of stars — may actually be more suitable for their survival regardless of the gravitational interactions thanks to the much shorter distances between planetary systems, allowing them to easily (relatively speaking) set up colonies on them.

[...] the proximity of all those stars may actually be an advantage for supporting life, says Rosanne Di Stefano, a theoretical astrophysicist at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts. Lots of closely packed stars could also mean lots of planetary systems not very far from one another. “If there is an advanced society in an environment like that, it could set up outposts relatively easily, because we’re dealing with distances that are so much shorter,” she says.

With such networking, civilizations in a globular cluster might endure for billions of years, and thus be available for humans to communicate with today or in the future.
