News Planetary Science Venus’ tectonics may be actively reshaping its surface The planet’s surface may be tectonically active in ways that are similar to Earth’s The 1989 Magellan mission captured images of Venus’ rounded mountain belts called coronae (four shown), which may be evidence of tectonic activity. JPL-Caltech/NASA By Nikk Ogasa 17 seconds ago Things may be moving on Venus’ surface. In 1983, researchers discovered that the planet’s surface was speckled with strange, circular landforms. These rounded mountain belts, known as coronae, have no known Earthly counterparts, and they’ve remained enigmatic for decades. But hot plumes of rock upwelling from Venus’ mantle are shaping the mysterious landforms, a new analysis suggests. If true, that mean that Venus’ surface is tectonically active, and not merely a stagnant layer, researchers report May 14 in Science Advances.
