Over time, that water has nearly all been lost. Figuring out how, when and why Venus lost its water helps planetary scientists like me understand what makes a planet habitable — or what can make a habitable planet transform into an uninhabitable world. Scientists have theories explaining why most of that water disappeared, but more water has disappeared than they predicted.
