Scientists believe the coloured downpour which lashed the state of Kerala had an extraterrestrial explanation. Analysis of a rain sample has confirmed the theory and more tests are now being carried out. The Centre for Earth Science Studies in Thiruvanthapuram reports a burning meteor threw more than 2,000 pounds of fine dust into the atmosphere. Earlier theories blamed the coloured rain on volcanic ash and Saharan dust brought by the south west monsoon. The incident has sparked a storm of copycat reports, including one of insects raining from the sky.
http://www.ananova.com/news/story/sm_367750.html Meteor rain theory dashed Ananova August 5, 2001 Scientists say "rainbow rain" that lashed parts of India may have been caused by a fungus, not meteor dust as first thought. Red, yellow, green and black rain fell in the state of Kerala last week. It had been thought the colours were down to a burning meteor throwing more than 2,000 pounds of fine dust into the atmosphere. But analysis of rain water samples now suggests fungal spores could be to blame. Indian Express reports a detailed chemical and biological analysis was carried out by scientists of the Centre for Earth Science Studies in Trivandrum. ''The red colour in the rain water appears to be mainly due to these spores," said CESS Director C S Baba. The biological study has revealed a red-coloured cell structure tentatively identified as spores of a type of fungus. The exact species has still to be found. The scientists though are clueless about what produced the huge quantity of spores, and how distribution was localised.
