Stable galactic neighborhoods, easy planet-hopping could provide long-term safe haven for life
KISSIMMEE, Fla. — Old, crowded star clusters might be the best place for an advanced civilization to survive in a harsh galaxy, a new study suggests.
Stable, long-lived stars in these clusters and the relative ease of hopping from one star system to the next could provide a safe space for any technologically savvy species that can leave its home and establish outposts around other stars. “The probability of a catastrophic event destroying such a civilization then becomes small,” said astronomer Rosanne Di Stefano. She presented the study January 7 at a meeting of the American Astronomical Society.
Globular star clusters pack hundreds of thousands of stars into balls just a few hundred light-years across. They’re also ancient; at over 10 billion years old, many have been around for as long as the galaxy. All of the
