Alien life could be present at the edge of our planet's atmosphere. At least so say the scientists will launch a mission that will search for bacteria that can live in those conditions.

This week, the British, in collaboration with the European Space Agency will launch a balloon containing atmosphere research tools. Bacteria and microorganisms are concerned, as it informs the Daily Galaxy.
They think it's possible that some microorganisms to be able to survive in conditions where the radiation is high. Also, the temperature is very low and the vacuum space is close.
Researchers assume that such organisms were made by asteroids and comets from space. It is also hoped that there will be discoveries of new types of bacteria that have been thrown into the atmosphere by volcanic eruptions.
The importance of this research is also linked with the origin of life on Earth. Daca vor reusi sa captureze ceea ce si-au propus, atunci se va adauga un nou argument teoriei conform careia viata pe planeta noastra ar fi fost adusa din alta parte a Caii Lactee.
Clara Juanes-Vallejo, who leads the team of researchers at Cranfield University, said: "There are theories that life on Earth came from space and, for this to be true, you should know that life can exist in such conditions in space. "
"Conditions are extreme in the stratosphere. Temperatures can reach -90 degrees Celsius and everything is close to vacuum. Also, the radiation is very harmful. If we learn that life is possible there, then it is possible on Mars and the asteroids" she said.
The mission is called CASS-E. The equipment was assembled in a sterile environment, typically used for missions to other planets such as Mars. Everything was well sealed so that no bacteria on Earth do not penetrate inside.
Teem will reach an altitude of over 33 km. The launch will make the Arctic Circle. We have taken the air, which will be passed through a series of filters to detect any microorganisms. All will reach the ground for review.
Other theories argue that life on Earth would have been brought from another part of the galaxy from asteroids and comets. Collisions have created unfavorable conditions, but these bacteria could have survived in the past subteran.Anul habitat in Indonesia has been an explosion believed to have been caused by an asteroid.
Some scientists believe that these celestial bodies, which disintegrate in the atmosphere leaves, however, following the forms of life.
