Is this evidence of alien life near Earth? Controversial scientist says he has found MORE organisms 25 miles above the planet Radical claim made by Dr Milton Wainwright from Sheffield University He used balloons to collect dust samples 25 miles (40km) above Earth Claims to have discovered ‘alien organisms’ that test positive for DNA His research has been widely criticised by the scientific community. Since 2013, Dr Milton Wainwright has been trying to convince the scientific community that he has found aliens in Earth’s stratosphere. Now the controversial British professor claims he has new evidence of these ‘extra-terrestrial organisms’ floating 25 miles (40km) above the planet. He says the organisms test positive for DNA, and have masses that are ‘six times bigger than the size limit of a particle which can be elevated from Earth to this height.’ The organisms, he claims, are contained in a microscopic metal globe designed by an intelligent species to ‘seed’ alien life on Earth. Dr Wainwright announced the discovery in an email to his students at Sheffield University, who posted it on Reddit. ‘We sent balloons and a sampler and found no pollen or grass, nothing up there to contaminate, it was completely pristine,’ Dr Wainwright told Jason Koebler at Motherboard. ‘For these reasons, we think [the organisms] are coming from space,’ he added. ‘All the time when you walk outside, you are being pelted with organisms that come from space.’ He said that his latest discoveries has been accepted in an ‘international astrobiology journal’ but hasn’t revealed which one. Dr Wainwright has yet to respond to DailyMail. Dr Wainwright’s research has been widely criticised by the scientific community as being backed by poor and flimsy evidence. Earlier this year, the astrobiologist revealed an image of what he said was a tiny metal ball spewing out a ‘gooey’ substance in samples gathered by a balloon in the Earth’s stratosphere.
