Paradise Lost

Venus today is a world of crushing heat and acid clouds, but the evidence written in its own atmosphere suggests it wasn't always that way. Scientists have found a chemical fingerprint in Venus's sky pointing to a planet that may have hosted liquid water oceans for billions of years, potentially making it the first habitable world in our solar system. There are competing theories about how that ancient water was lost and whether Venus was ever truly wet at all, and the scientific debate is far from settled. What both sides agree on is that at some point, Venus underwent a catastrophic transformation that turned whatever it once was into the hellscape we see today. And if life had the chance to emerge during those billions of potentially habitable years, the haunting question remains: where did it go?
