Looking for alien civilizations? Check these star clusters, scientists say.

(WASHINGTON POST)  January 5, 2016 — It’s purely theoretical, but it’s a really cool idea.

If we want to find intelligent aliens with advanced, space-faring civilizations, it would make sense for us to start in densest stellar neighborhoods. That’s the idea behind research presented Wednesday at the annual meeting of the American Astronomical Society.

Led by Rosanne Di Stefano of the Harvard-Smithsonian Center for Astrophysics, the research focuses on intense packs of stars called globular clusters, about 150 of which hover on the outskirts of the galaxy. Globular clusters are about 10 billion years old, making them nearly as old as the Milky Way itself, and can contain, on average, about a million stars in just 100 light years of space.
