Science Saturday II: Spaced Out Rainwater

Speaking of aliens, Godfrey Louis believes that the microbes in the the reddish rainwater that he is studying in his laboratory may be from outer space.

Louis, a solid-state physicist at Mahatma Gandhi University in southern India, has published a paper in the prestigious peer-reviewed journal Astrophysics and Space Science in which he hypothesizes that the samples -- water taken from the mysterious blood-colored showers that fell sporadically across Louis's home state of Kerala in the summer of 2001 -- contain extraterrestrial bacteria.

He has isolated strange, thick-walled, red-tinted cell-like structures about 10 microns in size. Stranger still, dozens of his experiments suggest that the particles may lack DNA yet still reproduce plentifully, even in water superheated to nearly 600 degrees Fahrenheit . (The known upper limit for life in water is about 250 degrees Fahrenheit .)

So how to explain them?

Louis speculates that the particles could have adapted to the harsh conditions of space and hitched a ride on a comet or meteorite that later broke apart in the upper atmosphere and mixed with rain clouds above India.

If his theory proves correct, the cells would be the first confirmed evidence of alien life and, as such, could yield tantalizing new clues to the origins of life on Earth.
