A new study reveals overlooked signs of geological activity on Venus — clues that the planet's mysterious surface is still changing today. These signs, found in giant circular features called "coronae," may not only reshape our understanding of Venus, but also offer a glimpse into Earth's own ancient past.
Coronae are vast, oval-shaped structures ranging in size from dozens to hundreds of miles wide. They are believed to form when hot, plumes from deep inside a planet push against its outer shell called the lithosphere. Imagine a slow-motion bubble of molten rock pressing upward beneath the surface, warping and cracking the crust above.
