We’ve Been Invaded by Aliens–Bacteria, That Is
A team of international researchers claims to have found what could be the first proof of life beyond our planet: clumps of extraterrestrial bacteria in the Earth?s upper atmosphere. Although they are similar to bacteria on Earth, the scientists say the living cells found in samples of air from the edge of the planet?s atmosphere are too far away to have come from Earth.
?There is now unambiguous evidence for the presence of clumps of living cells in air samples from as high up as 25 miles, well above the local tropopause, above which no air from lower down would normally be transported,? says Professor Chandra Wickramasinghe, an astronomer at Cardiff University in Wales. ?A prima facie case for a space incidence of bacteria onto the Earth may have been established.? read more
