China News Service, July 21. According to the British "Guardian" report, scientists have discovered 37 volcanic structures that may be active "in the near future" on Venus. This discovery shows that Venus is not a "dormant world" as previously thought.
According to reports, the researchers said that the focus of this research is on the ring structure called the crown. This structure is formed by the upwelling of hot rocks inside Venus. This proves that there are plates and magmatic activity on the surface of Venus in the "near term". It is reported that this research was published in the journal "Nature Earth Science".

For a long time, many scientists have believed that in the past 500 million years, Venus lacked plate movement and was geologically dormant.
"Our work shows that even today, some internal heat can still reach the surface of (Venus). Venus is clearly not dead or dormant as previously thought." Gul, Earth and Planetary Scientist at the Zurich Institute of Geophysics (Anna Gülcher) said. Gulcher is also the first author of this study.
According to the report, scientists studied the radar images of Venus taken by NASA's Magellan spacecraft in the 1990s. Among the 133 coronas analyzed, 37 of them appeared to be in the past 200. Used to be active in 10,000 to 3 million years. According to reports, this period of time is just a blink of an eye by geological standards.
"In my opinion, many of these structures are still active today," said Laurent Montesi, a geophysicist at the University of Maryland and one of the research authors.
It is reported that Venus is the planet closest to the earth, its surface is covered by sulfuric acid clouds, and the temperature is high enough to melt lead.
