But while the chances of finding life on its surface are slim, scientists have now uncovered a possible new place where some of the hardiest organisms might survive.

By analyzing radar images captured by the SAR instrument aboard NASA's orbiting Magellan spacecraft, researchers from the University of Trento were able to discover a subterranean cavern beneath the surface of Venus - most likely a dormant lava tube.The find not only provides further evidence of how volcanism has shaped Venus but also offers a potential new place for study and exploration - a hidden, subterranean world that nobody has ever seen before.

"Our knowledge of Venus is still limited, and until now we have never had the opportunity to directly observe processes occurring beneath the surface of Earth's twin planet," said research co-ordinator Lorenzo Bruzzone.

"The identification of a volcanic cavity is therefore of particular importance, as it allows us to validate theories that for many years have only hypothesized their existence."

"This discovery contributes to a deeper understanding of the processes that have shaped Venus's evolution and opens new perspectives for the study of the planet."
