At the edges of our galaxy, tens of thousands of , massive, dense clusters of stars glom together like a humongous interstellar house party. This is where, according to astrophysicists from the Harvard-Smithsonian Center for Astrophysics, we might find intelligent alien life.

The CFA's lead author, Rosanne DiStefano made this hypothesis at a meeting of the American Astronomical Society on Wednesday, and — believe it or not — her logic checks out.

Let's say finding intelligent life is a hypothetical one-in-a-million chance. By the center's estimation, there are 150 globular clusters in our Milky Way galaxy, each holding roughly a million stars per 100 million light years. Plus, they're old — like, 10 billion years old — and stable, meaning they didn't get nailed by .

It could be that these globular clusters are full of planets twice as old as our own, that had billions more years to develop. The Fermi paradox, a theory of why alien life hasn't found us yet, refers to these clusters as Planet X.

To date, according to the center, only one planet has been found in a globular cluster. This may be because, according to current theories, the globular clusters in our galaxy don't have the heavy elements to build stable planets.

But DiStefano and her colleague, Alak Ray from the Tata Institute of Fundamental Research in Mumbai, said it's premature to say there aren't planets in these clusters. Exoplanets, or planets that orbit a stars other than our own, have been found near stars that have just one-tenth of the heavy elements of our own sun.

In fact, if these globular clusters do have planets, they're probably extremely close together. That means those planets could communicate much easier with one another than with Earth. "We call it the 'globular cluster opportunity,'" DiStefano said on Wednesday. "Sending a broadcast between the stars wouldn't take any longer than a letter from the U.S. to Europe in the 18th century."

So there could be a chance that Earth is missing out on a huge game of galactic Telephone that's being played on the edge of the Milky Way, with intelligent societies working together to noticeably expand farther into the universe. But according to Robin Hanson, a research associate at Oxford University's Future of Humanity Institute, that would've happened by now.

"If there were life thousands of light years away, it could've been around for millions or billions of years," he told Mic. "If someone is alive out there, they would've long since developed as much as they can. If they didn't spread out [to Earth], it means they're stuck. And just being near other civilizations [in the globular cluster] doesn't make them any less stuck, no matter how much they developed economically and socially."
