Does Venus host alien life? That’s the big question after a recent study spotted phosphine — a gas with possible biological origins — in the planet’s clouds. We won’t have answers until further investigation, but clues to the planet’s history of habitability could be closer than expected.
Yale University astronomers Samuel Cabot and Gregory Laughlin said we should look to the moon for a peek into Venus’ past. They explained why in a paper accepted into the Planetary Science Journal this month.
The study suggests “asteroids and comets slamming into Venus may have dislodged as many as 10 billion rocks and sent them into an orbit that intersected with Earth and Earth’s moon,” Yale said in a statement. These impacts were more common billions of years ago, meaning bits of ancient Venus could remain
