Blood rain in India



More than 500,000 cubic meters of rainwater pouring in to a earth is red. At initial scientists suspicion which a red sleet was caused by dusty sand, though a scientists detected something startling, red elements in a H2O have been vital cells, cells which did not come from a earth!

Actually, from July 25 to September 23, 2001, red rain sporadically fell on the southern Indian state of Kerala. Heavy downpours occurred in which the rain was colored red, staining clothes pink. Yellow, green, and black rain was also reported. Colored rain had been reported in Kerala as early as 1896 and several times since then.[5]
It was initially thought that the rains were colored by fallout from a hypothetical meteor burst, but a study commissioned by the Government of India concluded that the rains had been colored by airborne spores from locally prolific terrestrial algae.

It was not until early 2006 that the colored rains of Kerala gained widespread attention when the popular media reported that Godfrey Louis and Santhosh Kumar of the Mahatma Gandhi University in Kottayam proposed a controversial hypothesis that the colored particles were extraterrestrial cells.


Several groups of researchers analyzed the chemical elements in the solid particles and different techniques gave similar results. The particles were composed mostly of carbon and oxygen with lesser amounts of hydrogen, nitrogen, silicon, chlorine and metals.

The samples of water were brought to the Centre for Earth Science Studies (CESS) in India, where they separated the suspended particles by filtration. The pH (acidity) of the water was found to be around 7 (neutral), which is the pH for normal rain water. The electrical conductivity of the rainwater showed the absence of any dissolved salts. Sediment (red particles plus debris) was collected and analyzed by the CESS using a combination of ion-coupled plasma mass spectrometry, atomic absorption spectrometry and wet chemical methods. The major elements found are listed below.[5] The CESS analysis also showed significant amounts of heavy metals in the raindust, including nickel (43 ppm), manganese (59 ppm), titanium (321 ppm), chromium (67ppm) and copper (55 ppm).



History records many instances of unusual objects falling with the rain — in 2000, in an example of raining animals, a small waterspout in the North Sea sucked up a school of fish a mile off shore, depositing them shortly afterwards on Great Yarmouth in the United Kingdom.[16] Colored rain is by no means rare, and can often be explained by the airborne transport of dust from desert or other dry regions which is washed down by rain. "Red Rains" have been frequently described in southern Europe, with increasing reports in recent years. One such case occurred in England in 1903, when dust was carried from the Sahara and fell with rain in February of that year.

At first, the red rain in Kerala was attributed to the same effect, with dust from the deserts of Arabia initially the suspect.[8] LIDAR observations had detected a cloud of dust in the atmosphere near Kerala in the days preceding the outbreak of the red rain. However, laboratory tests from all involved teams ruled out the particles were desert sand.
K.K. Sasidharan Pillai, a senior scientific assistant in the Indian Meteorological Department, proposed dust and acidic material from an eruption of Mayon Volcano in the Philippines as an explanation for the colored rain and the "burnt" leaves. The volcano was erupting in June and July 2001 and Pillai calculated that the Eastern or Equatorial jet stream could have transported volcanic material to Kerala in 25–36 hours. The Equatorial jet stream is unusual in that it flows from east to west at about 10° N, approximately the same latitude as Kerala (8° N) and Mayon Volcano (13° N). This hypothesis was also ruled out as the particles were neither acidic nor of volcanic origin, but were spores.


A study has been published showing a correlation between historic reports of colored rains and of meteors; the author of the paper, Patrick McCafferty, stated that sixty of these events (colored rain), or 36 %, were linked to meteoritic or cometary activity. But not always strongly. Sometimes the fall of red rain seems to have occurred after an airburst, as from a meteor exploding in air; other times the odd rainfall is merely recorded in the same year as the appearance of a comet.
