Mysterious red cells might be aliens

As bizarre as it may seem, the sample jars brimming with cloudy, reddish rainwater in Godfrey Louis's laboratory in southern India may hold, well, aliens.
In April, Louis, a solid-state physicist at Mahatma Gandhi University, 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 microbes from outer space.
Specifically, Louis 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 be extraterrestrial bacteria adapted to the harsh conditions of space and that the microbes 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.
Last winter, Louis sent some of his samples to astronomer Chandra Wickramasinghe and his colleagues at Cardiff University in Wales, who are now attempting to replicate his experiments; Wickramasinghe expects to publish his initial findings later this year.
Louis's theory holds special appeal for Wickramasinghe. A quarter of a century ago, he co-authored the modern theory of panspermia, which posits that bacteria-riddled space rocks seeded life on Earth.
