Globular Star Clusters May Contain Alien Life
Alien life does exist, believe scientists. Their eyes are set on globular star clusters, which are strange astronomical phenomena on the outer limits of the Milky Way. This is the region that is most likely to nurture alien life, according to the Daily Mail.
At present, the Milky Way has approximately 150 globular star clusters. Almost all are situated on the outskirts, with each one being very dense and harbouring one million stars in a little ball measuring just an average of 100 light-years across.
These are age-old astronomical regions almost as old as the Milky Way. Every one of them has an average lifespan of about 10 billion years.
"A globular cluster might be the first place in which intelligent life is identified in our galaxy," said Rosanne DiStefano of the Harvard-Smithsonian Center for Astrophysics (CfA).
Even if there are planets here, the stars would be "small and tranquil and lack any potential supernovas", according to National Geographic.
"In a way, it would be very serene to live in a globular cluster," said DiStefano.
So far, just one planet has been located in the cluster though. DiStefano believes we should just keep searching for more, according to NBC News.
The research was presented by DiStefano at a meeting of the American Astronomical Society on Jan. 7,2016.
