A group of scientists from the esteemed Harvard University have announced that aliens may exist on planets that are part of ancient solar systems, according to Mirror.co.uk. The scientists think that alien life could exist on these cluster that are billions of years more advanced than us: Globular clusters – dense balls of ancient stars at the outermost edge of the galaxy – may be the best places to look for alien civilisations, an expert has claimed. For many reasons, the distant regions might be favourable locations for intelligent life, astrophysicist Dr Rosanne Di Stefano believes. One is their age. Globular clusters, situated in the “halo” that extends beyond the Catherine wheel arms of Milky Way, contain stars estimated to be at least 10 billion years old – ample time for life to evolve to an advanced level. Another is that their stars are so close together. It takes just a month or so for light waves to travel between neighbouring stars in one of the clusters. In comparison, the nearest star to the Earth is 4.2 light years away. “It would also be easier for a civilisation to explore and even set up outposts on other worlds,” according to Dr Di Stefano, from [...]
