jdfox writes "World Science is reporting on a controversial paper to be published shortly in the peer-reviewed research journal Astrophysics and Space Science, describing a strange red rain that fell in India in 2001, shortly after a meteor airburst event in the area. The authors posit that the red particles found in the raindrops may be extraterrestrial microbes. The authors' last two papers on the subject were unpublished: this published paper is more cautious. The paper can be viewed online, and should obviously be considered in context. More info on the 'panspermia' hypothesis can be found at Wikipedia."
