A number of cases of yellow colored rain occurred in Kerala, India in July-August 2001 along with the red rain phenomenon. Recently during the end of July 2008 a few cases of yellow colored rain again occurred in Kerala and during the same time, unusual rain, termed as "blood rain" occurred in Bagado, Colombia. In this paper we show that the yellow rain and red rain can have a common origin. The yellow rainwater also exhibits the same unusual autofluorescence reported earlier for the cultured… Expand

Autofluorescence characteristics of the red rain cells
Red rain cells are the microscopic biological cells which appear mixed in rain water in large quantity imparting visibly red color to the rain water in a strange event called red rain phenomenon. OurExpand
Growth characteristics of red rain microbes at temperatures below 100 °C
The red rain microbes, which caused red rain phenomenon in Kerala, India, exhibit many characteristics much different from conventional microorganisms. Previous study indicates that these microbesExpand


The Red Rain Phenomenon of Kerala and its Possible Extraterrestrial Origin
A red rain phenomenon occurred in Kerala, India starting from 25th July 2001, in which the rainwater appeared coloured in various localized places that are spread over a few hundred kilometers inExpand
Unusual autofluorescence characteristic of cultured red-rain cells
The red cells found in the red rain in Kerala, India are now considered as a possible case of extraterrestrial life form. These cells can undergo rapid replication even at an extreme high temperatureExpand
Bloody rain again! Red rain and meteors in history and myth
Abstract In July 2001, red rain fell over Kerala in India shortly after reports of a meteor. When analysed, this red rain appeared to contain red cells, apparently demonstrating that such cells mustExpand
New biology of red rain extremophiles prove cometary panspermia
The study shows the absence of DNA in these organisms, indicating a new primitive domain of life with alternate thermostable genetics and supports the earlier argument that the mysterious red rain of Kerala is due to the cometary delivery of the red spores into the stratosphere above Kerala. Expand
