Microbes from Earth may survive on the moon, scientists find
Microbes from Earth might survive the harsh surface of the moon, albeit in a state of suspended animation, a new study finds. Previous research suggested the surface of the moon was too harsh for microbes to survive. Specifically, a 2019 study found ultraviolet rays and heat from the sun are the greatest barriers for microbial life on the lunar surface. However, this prior work did not account for the shelter that hills and valleys might supply on the moon. These could prove especially significant at the lunar poles, where the sun never climbs high in the sky, leading to permanently shadowed regions that can host ice — and perhaps more. In the new study, researchers analyzed three kinds of bacteria and two kinds of fungus. These are all commonly found on crewed space missions, and include microorganisms that prior work discovered were especially durable in the harsh conditions of space. Previo...
