2. Microbial Survivability in Space
Recent experiments aboard the International Space Station have revealed that certain microbes can withstand the extreme conditions of outer space. Exposed to intense radiation, vacuum, and dramatic temperature swings, some bacterial spores survived for months—and even years. This remarkable resilience suggests that tiny life forms could potentially hitch a ride on rocks or dust and endure interplanetary journeys. The European Space Agency continues to study how microbes adapt and persist, hinting at the possibility of natural panspermia events.
