Venus Might Harbor Enormous Subsurface Lava Tubes, Study Indicates

Using Finite Element Limit Analysis, researchers estimate Venus could host giant lava tubes hundreds of meters wide—up to about 1 kilometer (0.62 miles)—beneath its harsh surface, forming large subsurface channels; confirming them would require future missions like NASA's DAVINCI and VERITAS to image and probe the subsurface, though extreme conditions and funding debates may delay verification.
