New map catalogues more than 85,000 volcanoes on Venus

Radar imagery collected during Nasa's Magellan mission in 1990s used to develop volcano database

Our planet has more than 1,500 volcanoes - but if you think that's a lot then take a look at Venus. A new map, created from radar imagery collected during Nasa's Magellan mission in the 1990s, catalogues more than 85,000 volcanoes on Venus, 99% of which are less than 5km in diameter.

Our new database will enable scientists to think about where else to search for evidence of recent geological activity [on Venus]," says Paul Byrne from Washington University in St Louis.
