A new study conducted by Roseanne DiStefano from the Smithsonian Astrophysical Observatory indicates that alien civilizations dwell in brilliant star clusters. The old age of the planets in these star clusters, as well as the small distance between them are the two factors determining scientists to think that these space regions could hold alien life.
The U.S. government announced in 2015 that they will support the research that NASA is making to find alien life and structures in space. Even so, searching for new life forms in space is like looking for the needle in haystack without clear evidence where these forms of life might be hiding.
As a result, Roseanne DiStefano and her colleague Alak Ray from the Tata Institute in Mumbai have set out to identify the most suitable regions for alien life. According to the two and the scientific measurements they have made, alien civilizations could be hiding in the star clusters near our Milky Way.
These globular clusters can hold millions of stars and they were probably formed around 10 to 12 billion years ago. The old age of the globular clusters, as well as the small space existing between them prevented scientists from agreeing that these space formations are proper for alien civilizations.
In their opinion, the large presence of heavy elements in these star clusters do not allow the formation of new planets. If they did exist, the planets in this highly metallic environment would not allow the development of new forms of life, previous astronomical studies have argued.
Roseanne, on the other hand, does not think that high metallic content and the merging between the gravitational fields of each and every planet can affect the development of alien civilizations. Jupiter and its orbiting planets are a clear example that a highly metallic planet (Jupiter) can be surrounded by non-metallic habitable planets. Moreover, red dwarfs can further increase the probability of habitable planets within globular clusters, the scientist has further explained.
DiStefano and Ray have concluded, based on the recent research they have made, that the advanced age and the close vicinity of the celestial bodies in the globular cluster are factors that can favor alien life. For starters, alien civilizations have had billions of years to accommodate to conditions in these regions. Secondly, the proximity of the planets might enable them to quickly travel from one planet to another.
While these are just hypotheses that need to be further verified in the future, they offer a good starting point for the study of alien life in space. The study was presented at the 227th meeting of the American Astronomical Society in Florida.
