Alien microbes on meteorites. Conceptual artwork of a magnifying glass examining microbes on the surface of meteorites. It is thought that micro-organisms could survive the harsh conditions of space transported on the surface of space debris, such as comets and meteorites. These micro-organisms may form life on other planets if there are suitable conditions. The panspermia theory suggests the idea that life on Earth originated in this manner.
