Venusian atmosphere

On this day in space! Oct. 8, 1992: NASA's Pioneer Venus probe burns up in Venusian atmosphere after 14 years orbiting the planet

A new modelling study finds that roughly 100 microbial cells per year may be delivered to Venus's clouds via rock ejected from Earth by asteroid impacts, suggesting that if life is ever discovered in the Venusian atmosphere, it could have originated on Earth.
