Venus has lengthy been often called a house to loads of volcanoes - however not fairly this many.

A brand new map of the red-hot planet, which has a floor temperature of about 450C (842F), reveals there are round 85,000 scattered over its panorama.

That's nearly 50 instances greater than previous surveys had counted.

The large map, printed alongside analysis within the Journal of Geophysical Research: Planets, was constructed utilizing radar pictures taken by NASA's Magellan spacecraft.

Previous research had discovered proof of volcanic exercise on Venus, however the work by researchers at Washington University in St Louis marks the primary time Magellan's findings have been transformed into such an in depth map.

Co-author Paul Byrne mentioned it was "the most comprehensive map of all volcanic edifices on Venus ever compiled".

While the Washington staff doesn't know whether or not the volcanoes are energetic, the map may assist determine doable places for any future eruptions.

And there may very well be much more…

Lead writer Rebecca Hahn recommended the findings could be the tip of the magma cone.

The majority of the volcanoes mapped are lower than 3.1 miles extensive, which is taken into account fairly small.

It's why lots of them had gone unseen till now, with Ms Hahn utilising software program that wasn't obtainable when the Magellan information first turned obtainable to search out extra elusive volcanoes.

"People back then were manually hand-drawing circles around the volcanoes," she mentioned.

"I can just do it on my computer."

And Ms Hahn believes there may very well be much more, even smaller volcanoes strewn throughout Venus's floor, which can turn into seen with extra fashionable imaging tools.

Venus is already higher surveyed for volcanoes than Earth, as all of its volcanoes are on the floor.

On our planet, many are considered hidden beneath the oceans. We solely know for certain about 1,350 doubtlessly energetic volcanoes worldwide.

NASA and the European Space Agency are each making ready missions that may take photos of Venus at higher element than ever earlier than - the latter is aiming to launch in 2031.

Mr Byrne mentioned: "There are still a huge number of questions we have for Venus that we can't answer.

"We're simply getting began."
