Now, as New Scientist reports, researchers have confirmed that lava tubes also exist on Venus, our closest — and hellishly hot — planetary neighbor. Scientists have previously found that lava tubes tend to be larger when there’s less gravity, since their walls are less likely to collapse. “And then there’s Venus, completely disrupting this trend, displaying very, very big tube volumes.”“This is already giving away the fact that there’s likely something more on Venus playing a significant role,” she added. Over the years, astronomers have spotted holes and large pits dotting Venus’ surface, suggesting the existence of lava tubes.
