"Probing the limits of extremophilic life in extraterrestrial environment-simulated experiments"

TL;DR

This study demonstrates extremophilic microorganisms' resilience to radiation in simulated extraterrestrial environments, supporting the possibility of life transfer between celestial bodies through microlithopanspermia.

Contribution

It provides experimental evidence of extremophiles' resistance to radiation in space-like conditions, highlighting potential mechanisms for microbial survival beyond Earth.

Findings

Extremophiles resist radiation when protected by carbonaceous grains.

Data support the possibility of microbial transfer among habitable bodies.

Results suggest microbial life could survive in extraterrestrial environments.

Abstract

The results obtained in these experiments have revealed a remarkable resistance of extremophilic bacteria and archaea against different radiation sources (VUV, solar wind simulants, X rays) whenever protected by microsized carbonaceus grains. Altogether, the collected data suggest the interesting possibility of the existence of microbial life beyond Earth and its transfer among habitable bodies, which we have called microlithopanspermia.
