Magellan mission reveals possible tectonic activity on Venus
- A new study analyzing NASA's Magellan mission data reveals possible ongoing tectonic-like activity shaping Venus's surface through large features called coronae.
- Scientists investigated how Venus's surface deforms without tectonic plates and found that rising molten mantle plumes likely drive this tectonic-like activity.
- The research examined 75 coronae, discovering that 52 cap hot, buoyant mantle material which causes deformation and may recycle the planet's crust continually.
- Gael Cascioli explained that while coronae are not present on Earth today, they might have existed during the planet’s early history, prior to the development of plate tectonics.
- This discovery suggests Venus may share early tectonic processes with Earth and anticipates NASA's VERITAS mission to provide higher-resolution data in the 2030s.

NASA Finds Venus Has a Surprisingly Thin Crust – And Something Stranger
Venus may not have Earth-style tectonic plates, but it’s far from geologically quiet. A new model shows its crust is surprisingly thin and undergoes dramatic transformations, breaking off or melting into the mantle and potentially triggering volcanic eruptions. This crustal “metamorphism” gives scientists a whole new perspective on how Venus churns beneath its blistering surface. [...]
NASA Mission Reveals “Ground Shaking” New Insights into Mysterious Structures on Venus
A new analysis of mysterious structures on Venus known as coronae has revealed the likely presence of tectonic activity on the cloudy planet. While previous studies indicated Venus does not possess tectonic plates like Earth, the new analysis, which involved a fresh look at data collected by NASA’s Magellan mission, says the mysterious structures were likely caused by rising magma, inducing a tectonic shift in the planet’s upper mantle and crust…
