Title: Autofluorescence characteristics of the red rain cells
Abstract: 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. Our study of this phenomenon which happened in Kerala, India in 2001 has shown that the origin of these cells is possibly extraterrestrial. These cells are not so far successfully identified as any organism known on earth. The cells have unusual property like ability to reproduce at extreme high temperature and the colorless daughter cells cultured from the red cells show unusual autofluorescence characteristics. In this paper we report the autofluorescence characteristics of the original red rain cells. High resolution fluorescence microscopy is employed to study the fluorescence images of the cells under UV-Visible excitation. The results are discussed. © (2013) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE). Downloading of the abstract is permitted for personal use only.
