Red Rain

[5614]

In 2001, a mysterious red rain fell over parts of India. Scientists still do not have a full explanation of the colour -- there have been suggestions ranging from alien life to parts of a comet, but a recent analysis shows that they are actually a strange type of cell.

 

Researchers in England found that the particles contain DNA, although the DNA is different than any other they have analysed. The cells also have unusually thick walls and some contain "daughter" cells that are even more puzzling. Now it is up to scientists to work out if the cells are terrestrial, or possibly from space.
