Scientists are investigating panspermia—the theory that microbial life travels between planets on asteroids and dust grains—with new evidence showing microbes can survive impact crashes. Research suggests Earth may have been seeding Venus and Europa with microscopic organisms for billions of years, potentially explaining the origins of life beyond our planet.
·Studies demonstrate microbes can survive crash-landings on other planets, making interplanetary microbial transport feasible
·Earth may have been sending microscopic hitchhikers to Venus for a billion years through natural planetary processes
·If life exists in Venus's atmosphere, it could have originated from Earth rather than emerging independently
·Panspermia mechanisms could explain how life reached Jupiter's moon Europa on tiny grains of dust
·Impact survival research provides experimental support for panspermia as a viable theory of life distribution across the solar system
