Scientists from the United States and Switzerland have proven the continuation of active processes associated with mixing substances in the interior of Venus.
Nature Geoscience reported that, as is well known, the surface of Venus formed later after the surface of Mars or Mercury, two of which cooled long ago. The annular structures known as crowns indicate continued activity in the interior of Venus.
Experts believe that these structures were formed as a result of the flow of hot materials to the surface of the planet, similar to what results from volcanic activity on Earth.
Astronomers until recently believed that Venus had cooled and stopped the geological activity in its interior, and its shell has hardened to the point that no hot substance will penetrate it. But the results of the recent study conducted by scientists at the University of Maryland and the Institute of Geophysics in Switzerland, showed that there are 37 "crowns" on the surface of the planet, with signs indicating the continuation of volcanic activity.
"For the first time, we can confirm that these are not ancient volcanoes, but active volcanoes, which may now be inactive but not dead," says Professor Laurent Montese from the University of Maryland.
According to the Russian agency, Novosti, this study radically changes previous perceptions of Venus. And now we are saying this is not a rigid planet, because its interior is still active and new volcanoes may appear on its surface. "
The digital model of the thermal mechanical activity of the interior of the planet necessary for the formation of crowns, has shown that the difference of crowns on its surface reflects the stages of its geological development, which is still in its interior.
