The Extraordinary Tale of Red Rain, Comets and Extraterrestrials

Technology Review: Blogs: arXiv blog: The Extraordinary Tale of Red Rain, Comets and Extraterrestrials: "Panspermia is the idea that life exists throughout the universe in comets, asteroids and interstellar dust clouds and that life of Earth was seeded from one or more of these sources. Panspermia holds that we are all extraterrestrials.

While this is certainly not a mainstream idea in science, a growing body of evidence suggests that it should be carefully studied rather than casually disregarded.

For example, various bugs have been shown to survive for months or even years in the harsh conditions of space. And one of the more interesting but lesser known facts about the Mars meteorite that some scientists believe holds evidence of life on Mars, is that its interior never rose above 50 degrees centigrade, despite being blasted from the Martian surface by an meteor impact and surviving a fiery a descent through Earth's thick atmosphere.

If there is life up there, this evidence suggests that it could survive the trip to Earth."
