Panspermia

Index Panspermia

Panspermia is the hypothesis that life exists throughout the Universe, distributed by space dust, meteoroids, asteroids, comets, and planetoids, as well as by spacecraft carrying unintended contamination by microorganisms,Forward planetary contamination like Tersicoccus phoenicis, that has shown resistance to methods usually used in spacecraft assembly clean rooms: known as directed panspermia.
