Scientists Found Mysterious Structures on Venus — and They’re Surprised

Venus has always looked familiar and impossible at the same time. It is close to Earth in size and density, yet its surface is a crushing, overheated world hidden under thick clouds, making every new clue feel like a message from a planet we still barely understand.

Now scientists are looking again at strange circular structures scattered across Venus, known as coronae. These features have puzzled researchers for decades, but new analysis suggests they may be signs that Venus is not as geologically quiet as once assumed — and that deep forces inside the planet may still be reshaping its surface.
