Earth 'Surrounded By Bacteria Bubble'

Image
Planet Earth is surrounded by a bubble of live bacteria scientists have found.

According to a report by Popular Science the colonies of bacteria live at about 33,000 feet - roughly the cruising height of a passenger jet.

But while it might sound strange, it appears the phenomenon is a crucial part of the ecosystem in which we all live.

Scientists from Georgia Institute of Technology found that despite the atmosphere at that height being relatively thin, lacking in oxygen, freezing cold and high in UV radiation, bacteria are able to happily survive at that height.

The team reportedly flew a Nasa jet up to six miles above the Earth, and then collected particles from outside the plane.
