Paper Abstract

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 red rain microbes. Reasons for considering extraterrestrial origin for these colored rains are discussed.
