A recent study suggests asteroid impacts on Earth could have propelled microbes into space, allowing these tiny life forms to reach Venus and survive in its clouds. This challenges the idea that any life found on Venus originated there, raising the possibility it traveled from Earth.
The research highlights how microbes ejected from Earth might endure the harsh journey and settle in Venus' upper atmosphere, where conditions could allow survival.
If future missions detect life in Venus’ clouds, it may indicate Earth as its origin, not Venus itself.
