Harvard scientists believe that advanced Alien civilizations could inhabit ancient solar systems on the edge of our galaxy

According to interesting statements from a team of Harvard scientists, aliens could inhabit the ancient solar system located on the edge of our galaxy. There, according to Harvard researchers, the clusters have the potential to support life, which could be as much as billions of years more advanced than we are today.

Experts believe that so-called ‘Globular Clusters’ which are something like a dense sphere of ancient stars located at the outermost edge of our galaxy could be the best place where we should be looking for alien civilizations.

Dr Rosanne Di Stefano believes that there are numerous reasons why the distant regions of our galaxy might be extremely favorable locations to search for intelligent lifeforms.

According to Di Stefano, one of those reasons is the age. The Globular clusters located in the outermost regions of our galaxy, extending beyond the Catherine wheel arms of our Milky Way, contain stars which according to researchers could have an estimated age of at least 10 billion years, a very big time period for life to evolve to advanced levels.

Another favorable reason according to experts is the relatively close distance between the stars. This means that it takes about a month (Earth) for light waves to make it across the distances of neighboring stars in one of the many clusters.

Comparing it to our nearby distances, the nearest star to the Earth is 4.2 light years away.

“It would also be easier for a civilization to explore and even set up outposts on other worlds,” according to Dr. Di Stefano, from the Harvard-Smithsonian Centre for Astrophysics in Cambridge, US.

Our Sun is around 4.6 Billion years old, which means that if there are civilizations located in these globular clusters, they could be billions of years more advanced than we are today.

The only exoplanet so far discovered by researchers and located in globular clusters known as M4 in the Scorpius constellation is nicknamed Methuselah. The planet is believed to orbit a binary system of a pulsar and a white dwarf. The estimated age of Methuselah is believed to be 12.7 Billion years, making it the OLDEST exoplanet discovered on record.

Writing in the  BBC’s Sky At Night magazine, Dr. Di Stefano said: “It would be strange if there were not many others.

“Of course, this is all conjecture. We don’t know whether there is alien life in such clusters.

“But globular clusters would be a good place to look and might be the first place where intelligent life is identified in our galaxy.”

But, not everything is perfect for life evolving in globular clusters at the edges of the galaxy. Researchers point to possible drawbacks such as the stars could get too close to one another and disrupt each other’s planetary system, something that could be catastrophic for the evolution of life. However, Dr. Di Stefano conducted research which points to the fact that this danger does not exist.

She wrote: “What we’ve found is the opposite, that it’s possible for many habitable-zone planets to survive for billions of years.”
