Scientists have identified at least 37 volcanically active regions on Venus, suggesting that the planet may not be as geologically inert as previously expected. The discovery sheds light on a key mystery about Venus, a world that is notoriously difficult to study because of its thick cloudy atmosphere and hellish surface conditions.

Scientists led by Anna Gülcher, a geophysicist at ETH Zürich in Switzerland, modeled the planet’s “coronae,” which are circular structures that indicate geological activity, and compared those simulations to known surface features on Venus.
