Many scientists long had thought Venus, lacking the plate tectonics that gradually reshape Earth’s surface, was essentially dormant geologically for the past half billion years. "Our work shows that some of that interior heat is still able to reach the surface even today. Then they scoured radar images of Venus from NASA's Magellan spacecraft in the 1990s to find coronae that fit the bill. Of 133 coronae examined, 37 appear to have been active in the past 2 million to 3 million years, a blink of the eye in geological time. "In my opinion, many of these structures are indeed active today," said University of Maryland geophysicist and study co-author Laurent Montesi.
