Scientists discover Alien Bugs
The University of Sheffield experts sent a research balloon about 27km (16.7 miles) into the atmosphere during last month's Perseids meteor shower and found tiny organisms.
When the balloon landed back on the ground in Wakefield, West Yorkshire, the researchers detected microscopic bugs on it.
According to the scientists, they were unable to carry the samples from the Earth's surface into the stratosphere. They also said strict tests were conducted in order to avoid any sort of contamination of the samples.
The leader of the team from the University of Sheffield, Professor Milton Wainwright said, "Most people will assume that these biological particles must have just drifted up to the stratosphere from Earth, but it is generally accepted that a particle of the size found cannot be lifted from Earth."
According to Professor Milton Wainwright, the biological entities originated from space. The findings are yet to be published in the journal of Cosmology.
The researchers will carry out further experiments during a meteor shower in October and tests on the samples will also be planned accordingly.
As some of the samples were covered with cosmic dust, the group of scientists concluded that the particles are coming from comets, which are large balls of ice travelling through space at high speed.
