Venus features massive rift valleys that indicate the planet may still be geologically active. Their study, published in Nature Geoscience, adds to evidence that Venus remains geologically alive and might even host active volcanoes today. These vast cracks appear when a planet’s crust is pulled apart by forces deep within. Using a detailed 3D computer simulation, the team recreated how Venus’s rift valleys could develop. Unlike older, simpler models, these new simulations offered a more realistic view of how the planet’s crust behaves.
