Globular clusters are tightly packed groups of stars, 100 cubic lights year across or so, ranging from 10-12 billion yeas old. These tightly packed groups could harbor ancient, advanced life says the research submitted to at the 227th American Astronomical Society meeting Kissimmee, Florida this week.
The research submitted from the Tata Institute of Fundamental Research in Mumbai and the Smithsonian Astrophysical observatory is asking us to look at these areas that have been bypassed. Previous research showed the stars may be clumped too close together for planets to form, or survive even if they did; only one has been found so far. But Rosanne Di Stefano of the Harvard-Smithsonian Astrophysical Observatory says, “A globular cluster might be the first place in which intelligent life is identified in our galaxy.”
Even though it may be difficult for planets to form there, if they did, the immense amount of time for advanced life to develop compared to the other parts of the universe is enough that it might be the best candidate we have .
