Venus Has A Giant Volcanic Cave Beneath Its Surface
A University of Trento team re‑examined NASA’s 1990s Magellan radar data and identified a massive volcanic cave beneath the Nyx Mons region on Venus. The skylight‑like pit is roughly 1 km wide, with a 150 m thick roof, 375 m height and a 45 km‑long subsurface conduit. This marks the first direct evidence of a large lava tube on the planet and hints at a hidden network of similar structures. Researchers say forthcoming ESA EnVision and NASA VERITAS missions could map these features in detail.
