Venusian Rift Valleys May Explain the Planet's Persistent Geological Activity

Scientists analyzing high-resolution radar data have identified a network of rift valleys that cut across Venus’s surface. These structures appear to channel mantle heat toward the crust, sustaining volcanic eruptions and surface deformation. The study argues that this mechanism may keep Venus geologically active despite the absence of Earth-like plate tectonics. Findings were published in the journal Nature, highlighting a fresh perspective on the planet’s interior dynamics.
