Likely active volcanoes found on Venus, defying theory of dormant planet

Researchers identify 37 ring-like structures known as coronae that are believed to be living volcanoes

Scientists have identified 37 volcanic structures on Venus that appear to have been recently active – and probably still are today – painting the picture of a geologically dynamic planet and not a dormant world as long thought.

The research focused on ring-like structures called coronae, caused by an upwelling of hot rock from deep within the planet’s interior, and provided compelling evidence of widespread recent tectonic and magma activity on Venus’s surface, researchers have said.
