“In a way, it would be very serene to live in a globular cluster,” Di Stefano says. Di Stefano and her colleague Alak Ray, from the Tata Institute of Technology, simulated the stellar population of a cluster and determined where planets might be most likely to survive. Based on this hypothesis, a list of the most promising parts of the galaxy was completed. So in the future astronomers searching for noisy extraterrestrials might try looking in a most unexpected place: dense conglomerates of stars that appear to be largely empty of planets. Alien life and even advanced civilizations could be found.
