The find comes just weeks after a similar “seed particle” also thought to be some sort of infective agent was discovered in space samples.
It gives further weight to theories that not only are we not alone in the universe, but that aliens may be silently populating Earth.
He said the nature of the experiments which captured the particle means it could not have come from Earth.
It contain any traces of pollen, skin or human dandruff meaning its only source has to be extra-terrestrial, he insists.
“The ice melted as it drew closer to Earth leaving the contents.
“There is no pollen, skin or any other DNA-containing substance in this find which could have come from Earth yet it is entirely made up of DNA.
“We have no idea what this particle is.”
The particle was discovered on the surface of a testing balloon sent 25 miles into the sky over India in the highest such experiment to date.
Treatment with the substance DAPI, which stains genetic matter green, showed it to be rich in DNA – the code of life.
Professor Chandra Wickramasinghe director of the Buckingham Centre for Astrobiology at the University of Buckingham in England, who was involved in the find agreed it is further proof of alien life.
He said: “The biological mass is made up of extremely small so called “nano-forms”.
“The excitement over this research is that some of the DNA-rich particles are six times bigger than the size of particles which physics currently tells us can travel up from Earth.
“The fact that no pollen and grass was found inside our sampler alongside the DNA masses, means that they could not have been carried up from Earth.”
Professor Wainwright added: “These DNA masses are coming into the stratosphere from space.
“This is a conclusion that fits in with the team” recent findings showing unusual organisms migrating from space to this region.
“When this recent finding, plus our other results, published over the last two years, are taken as one we remain confident that life forms are continually entering the stratosphere from space.”
