There is a small bottle containing a red fluid on a shelf in Sheffield University’s microbiology laboratory. The liquid looks cloudy and uninteresting. Yet, if one group of scientists is correct, the phial contains the first samples of extraterrestrial life isolated by researchers.Inside the bottle are samples left over from one of the strangest incidents in recent meteorological history. On 25 July, 2001, blood-red rain fell over the Kerala district of western India. And these rain bursts continued for the next two months. All along the coast it rained crimson, turning local people’s clothes pink, burning leaves on trees and falling as scarlet sheets at some points.
Investigations suggested the rain was red because winds had swept up dust from Arabia and dumped it on Kerala. But Godfrey Louis, a physicist at Mahatma Gandhi University in Kottayam, after gathering samples left over from the rains, concluded this was nonsense. ‘If you look at these particles under a microscope, you can see they are not dust, they have a clear biological appearance.’ Instead Louis decided that the rain was made up of bacteria-like material that had been swept to Earth from a passing comet. In short, it rained aliens over India during the summer of 2001.
Not everyone is convinced by the idea, of course. Indeed most researchers think it is highly dubious. One scientist who posted a message on Louis’s website described it as ‘bullshit’.
But a few researchers believe Louis may be on to something and are following up his work. Milton Wainwright, a microbiologist at Sheffield, is now testing samples of Kerala’s red rain. ‘It is too early to say what’s in the phial,’ he said. ‘But it is certainly not dust. Nor is there any DNA there, but then alien bacteria would not necessarily contain DNA.’ – guarduk
