Microscopic algae found on the side of a research balloon is being hailed as evidence of alien life.
British astrobiologist Chandra Wickramasinghe believes that algae scraped from the sterile side of a high-altitude balloon could have only got there if it had come from space, a claim that backs up the theory that the 'seeds of life' are constantly being transferred around the cosmos on meteors, comets and other bodies.
The idea that life on Earth originated elsewhere in the universe, a theory known as panspermia, has been gaining momentum in recent years and could mean that not only are we ourselves extraterrestrial in origin but that the universe is likely to be teeming with life.
"Biological entities of this nature have not previously been reported occurring in the stratosphere," said Wickramasinghe. "If there is no mechanism by which these biological entities could be elevated from Earth to the stratosphere then it must have arrived from above the stratosphere and have been incoming to Earth."
