A recent modeling study indicates that asteroid impacts on Earth could have transferred microbial life to Venus over billions of years. Researchers presented findings at the 2026 Lunar and Planetary Science Conference showing that material from Earth might survive the journey and persist briefly in Venus' clouds.

An international team of scientists has modeled how complex organic molecules, essential for biology, could have been incorporated into Jupiter's largest moons during their formation. The research suggests these building blocks of life were delivered from the early solar system's gas and dust disk without significant chemical alteration. The findings appear in two recent scientific papers.

A new NASA study indicates that traces of ancient life on Mars could survive for over 50 million years in pure ice, protected from cosmic radiation. Researchers recommend future missions focus on drilling into clean ice deposits rather than rocks or soil. The findings, based on lab simulations, highlight pure ice as a potential preserve for organic material.
