British scientists claim to have found proof of alien life and of it arriving close to Earth after sending a balloon 27km into the stratosphere.
Professor Milton Wainwright, from the University of Sheffield’s department of molecular biology and biotechnology, has revealed that a specially designed balloon used to monitor the Perseid meteor shower has returned with samples of small organisms.
The Perseid meteor shower is a cloud comprising particles ejected by the comet Swift-Tuttle as it travels on its 133-year orbit.
Professor Wainwright said the particles collected by the balloon, a diatom fragment and some "unusual biological entities", were too large to have originated on Earth.
The conclusion is that they originated from space.
The researchers’ findings were published in the Journal of Cosmology.
Professor Wainwright said: "In the absence of a mechanism by which large particles like these can be transported to the stratosphere we can only conclude that the biological entities originated from space.
"Our conclusion then is that life is continually arriving to Earth from space, life is not restricted to this planet and it almost certainly did not originate here."
He said "stringent precautions" had been taken against contamination, news website metro.co.uk reported.
There are plans to launch another balloon to coincide with a meteor shower associated with Haley's comment.
