New evidence has been identified which confirms that Venus also has a incredibly hot interior.
Venus is the infernal planet of our Solar System.
The researchers determined the type of geological features that could exist only in a recently active corona - a telltale trench surrounding the structure. "This study significantly changes the view of Venus from a mostly inactive planet to one whose interior is still churning and can feed many active volcanoes".
Venus, Earth's closest and just somewhat scaled-down planetary neighbor, is included by clouds of sulfuric acid and has floor temperatures sizzling enough to melt lead.
"This is the very first time we are capable to point to precise structures and say, 'Look, this is not an historical volcano but just one that is active these days - dormant, most likely, but not dead, '" research co-writer Laurent Montési, a professor of geology at the University of Maryland, claimed in a statement.
They have formed where plumes of hot magma from deep inside the planet make their way up through the planet's mantle and crust - not unlike how the volcanic Hawaiian Islands formed on Earth.
Scientists have discovered 37 volcanic constructions on Venus that show up to be not long ago lively - and probably nevertheless are right now - painting the photo of a geologically dynamic planet and not a dormant planet as very long assumed. Earth's surface is reshaped by tectonics, the similar ones found on Venus. The volcanic sites of the planet are, on average, 300 kilometers in diameter, while the largest active volcano on our planet, located in Mauna Loa, Hawaii, is only 120 km. To understand this training process, researchers numerically modelled the thermo-mechanical activity within Venus.
This suggests there are some areas where the planet is most active than in others - providing clues to the workings of the interior of Venus. But the new study suggests otherwise.
Evidence of a warm interior and geologic activity dots the surface of the planet in the form of ring-like structures known as coronae. According to the researcher, previous investigations have already indicated that the planet has active volcanoes.
Much of the data the researchers have to work with has poor resolution, so future missions to Venus like the European Space Agency's EnVision launching in the 2030s and NASA's proposed VERITAS mission concept could provide more high-resolution data of the planet's geodynamics and topography.
