Venus: An Active Planet Even Today?

Picture a world that, for decades, was considered geologically dormant—yet recent discoveries turn that assumption on its head. Thanks to detailed analysis of data from NASA's Magellan spacecraft, launched back in the 1990s, scientists now believe Venus may still be experiencing profound internal activity. These clues come in the form of gigantic structures known as coronae—massive, concentric, bulls-eye-shaped features that stretch across vast swaths of the planet's surface. They resemble scars from a planet still in the throes of internal upheaval. In essence, hot mantle plumes—bubbles of buoyant, molten rock—may be rising from deep within Venus's core and pushing against its crust, causing surface deformation. The gravity measurements tell us that these plumes are still active; this implies that beneath Venus’s thick atmosphere, a restless, dynamic interior persists—perhaps similar to Earth's early, fiery stages, which makes this discovery all the more compelling and revolutionary.

Coronae: Surface Clues to a Roaring Inner World

Coronæ are more than just large surface features; they are vivid evidence of the planet’s ongoing geological activity. These enormous formations—beautiful in their size but formidable in their implications—are like planetary fingerprints, each telling a story of internal processes. For example, the Artemis and Quetzalpetlatl coronae exhibit telltale signs of uplift and fracturing caused by rising hot mantle material. The gravity data confirms these are not passive features—they are the surface expressions of plumes of buoyant, heated rock still stirring deep beneath Venus’s crust. It’s as if the planet is gently flexing, slowly but persistently, like a giant beast still alive and thrashing beneath its calm exterior. This ongoing activity suggests Venus is not merely a relic of the solar system but a planet with an active, evolving interior—possibly similar to Earth's own early, chaotic days before tectonic plates stabilized and spread apart.
