A new analysis of data collected on Venus more than 30 years ago suggests the planet may currently be volcanically active.

A research group from Italy led by David Sulcanese of the Università d’Annunzio in Pescara, Italy, has used data from a radar mapping of Venus’s surface taken in the early 1990s to search for volcanic lava flow, finding it in two regions.

The discovery suggests that volcanic activity may be currently active and more widespread than was previously thought, support...

Models show Venus’ superheated core could produce extended volcanism, long-lived resurfacing. A Southwest Research Institute-led team has modeled the early impact history of Venus to explain how Earth’s sister planet has maintained a youthful surface despite lacking plate tectonics. The team compared the early collision histories of the two bodies and determined that Venus likely experienced higher-speed, higher-energy impacts creating a superheated core that promoted extended volcanism and resurfaced the planet.
