For generations, Venus was written off as a geologically inert world, its violent surface a relic of a distant past. New three-dimensional simulations from ETH Zurich now suggest otherwise: some of the planet's vast rift valleys may have formed recently and could still be widening today, driven by an interior far more restless than science had assumed. This quiet revision of a planetary biography reminds us how much our certainties about neighboring worlds remain provisional, and how a single shift in modeling technique can reopen questions we thought were long settled.
