Earth-to-Venus Panspermia: Life Could Reach Venus' Clouds
New modeling using the Venus Life Equation suggests Earth-origin material can survive ejection, travel to Venus, and disperse in Venus’ clouds, with hundreds of billions of Earth‑origin cells potentially transferred and some remaining viable; while not proving life exists there, the study shows Earth–Venus panspermia is plausible and could imply any Venus cloud life might have Earth origins.
