Plankton Found on the Exterior of the International Space Station!
While examining samples taken from the exterior surface of the ISS, scientists discovered something completely unexpected - Marine Plankton living on the surface, despite the harsh condition (Vacuum, temperature, and radiation.)
There was evidence that the plankton had been living there for years, and possibly even developing, too.
This gives more plausibility to the panspermia theory - that life all over the solar system/galaxy/universe is all related thanks to bacteria catching rides on asteroids and comets. We already know it is possible for rocks to be thrown away from a planet by something like an asteroid impact or large volcanic eruption - some meteorites have had their lineage traced back to mars.
So do you believe the panspermia theory to be plausible? what about alien life in general?
