New research suggests that the dark, shadowed regions of the Moon may harbor microbial life due to their protective conditions from UV radiation and extreme temperatures. These permanently shadowed regions (PSRs) could act as microbial freezers, preserving organic molecules for decades and potentially complicating efforts to explore and study the lunar environment. Concerns about contaminating the Moon with Earth germs are heightened, as past spacecraft impacts and the potential for surviving microbes in PSRs could set back lunar ambitions for generations.
