Long regarded as a geologically dormant planet, Venus is showing signs of internal activity. Scientists using 3D computer models have found evidence that enormous rift valleys on Venus may have formed relatively recently and could still be spreading, indicating a more dynamic interior than once thought.
- Venus’s giant rift valleys may be geologically young.
- New 3D models show rifts could widen by centimeters per year.
- Findings challenge the view of Venus as a dormant world.
What happened
Scientists from ETH Zurich have developed the first high-resolution, three-dimensional computer simulations of Venus’s massive rift valleys. Led by Taras Gerya and including lead author Xi Yang, the research used advanced modeling to better understand how these enormous geological structures formed and evolved.
Their findings show that some rift valleys on Venus are likely younger than previously believed and may still be actively spreading at rates of 3 to 10 centimeters per year. This challenges earlier assumptions that these features were ancient and static for over 100 million years.
Why it feels good
Discovering that Venus may still be geologically active reshapes our understanding of the planet and its potential for ongoing dynamic processes beneath the surface. It shifts the narrative away from Venus as a completely dormant, static world to one that could still be changing and evolving.
This advancement also brings hope for future missions, such as ESA’s EnVision orbiter, which will study Venus’s surface in detail. Pinpointing areas of geological activity could open new opportunities for uncovering signs of volcanism or tectonic movement, deepening our knowledge of rocky planet evolution.
What to enjoy or watch next
The new research offers vital clues that will guide upcoming space exploration missions focused on Venus. The EnVision mission, slated for launch in the early 2030s, will use instruments developed with the help of ETH researchers to probe the planet’s surface and its internal activity in unprecedented detail.
For space enthusiasts and planetary scientists, the evolving story of Venus remains an exciting frontier. Watching how new data and missions confirm or expand on these findings promises to enhance our understanding of Earth's nearest planetary neighbor and rocky planets beyond our solar system.
