On June 28, 2012 in the city of Kannur, Kerala, India, a very unusual rainfall fell for 15 minutes - rain of bright red color. Red puddles formed on the roads of the city of Kannur, and the clothes of passers-by instantly turned red.
Local residents were very alarmed by this, as they had previously witnessed red rain - this natural disaster happened in India back in 2001 (on video).
This phenomenon was first recorded in Kerala, India just hours after the meteors fell in July 2001, so astrobiologist Godfrey Louis of the Cochin University of Science and Technology (CUSAT) suggested that the rain was colored red because of the smallest dust that fell to the Earth from the comet fragments.
In the course of laboratory analysis, when studying samples of red rainwater, its strange properties were found - fluorescence, which was emitted by cellular structures similar to mitochondria. Godfrey Louis is convinced of the extraterrestrial origin of these cellular structures, which have colored the water red because comets can have a hot core of water and chemicals that can contain microorganisms and such cellular structures.
According to Godfrey Louis, these "extraterrestrial" cellular structures resemble ordinary cells, but they do not contain DNA molecules, but biochemical processes also take place in these cells and the cellular structures from red rain can withstand very high temperatures, up to almost 300 degrees Celsius. However, it is not yet clear how they can interact with normal life forms on Earth.
