Researchers at the University of Sheffield and University of Buckingham Centre for Astrobiology have discovered an oddly microscopic structure in the outer reaches of the Earth's atmosphere, which hints at the existence of alien life. The living balloon that supposedly carried microscopic alien organisms has been tagged as "ghost particle".

Researcher Milton Wainwright insists that the particle is biological in nature and is made of carbon and oxygen, reports ANI. This new discovery adds on to the proof that alien life exists, claim Wainwright and his team that gathered the particle. 

Collected from the stratosphere amid dust and particulate matter, the ghost particle, as wide as a human hair and a ghostly appearance, is said to resemble a chiffon scarf or a wisp of smoke under the microscope. 

In the picture, the ghost particle looks like a deflated balloon, but Wainright speculates that in its natural state it is probably inflated and resembles nothing that has been previously found on Earth. Researchers also believe that the "living balloon", which is expected to be lighter than air gases, could float in the air or seas of an unknown space environment.

The "absolutely pristine condition" in which it was found, sans the contamination of pollen, grass or pollution particles, also reinstates their space origin. "Unless a means of lifting them from Earth exists which selectively sieves them out from other Earth-derived debris then they must be incoming from space."
