Volcanoes On Venus (Possibly)
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.
Very interesting – I’ve read a hypothesis suggesting that plate tectonics are only possibly on earth due to the oceans providing the lubrication.
