Space.com: Advanced Alien Civilizations Could Live in Globular Star Clusters
KISSIMMEE, Fla. — Densely packed groups of stars may make excellent cradles for complex space-traveling life to evolve. Despite studies that claim these environments, known as globular clusters, may be too harsh for life, a new study argues for a more optimistic view based on the evolving understanding of where planets lie outside the solar system.
"A globular cluster might be the first place in which intelligent life is identified in our galaxy," lead study author Rosanne Di Stefano, of the Harvard-Smithsonian Center for Astrophysics, said in a statement. Di Stefano presented the new research today (Jan. 6) here at the 227th meeting of the American Astronomical Society.Globular clusters are massive groupings of millions of stars in a region only 100 light-years across. The clusters date back to the early life of the Milky Way — nearly 10 billion years ago. (For comparison, the universe is approximately 13.7 billion years old.) Although these clusters' age raises some questions, it also provides ample time for civilizations that emerged to evolve and become complex.
