Like Earth, the volcanoes of Venus are still energetic


A joint Swiss-American research team has announced a group of the best evidence so far that Venus is geologically active, and it is the first time in the history of the study of this planet where specific places where active and fresh volcanoes have been identified.

Modern volcanoes

And to reach these results – which were published in the journal “Nature Geoscience” (Nature GeoscienceIt was announced on July 20 – the team used mathematical models to examine the mechanical thermal activity beneath the surface of Venus, which helped them create a high-resolution 3D simulation of features of regions on the planet called “wreaths.”

Wreaths are annular openings above the surface of the planet, from which fumes from the planet’s inner layers emerge, but they were believed to be only remnants of ancient volcanic activity.

But according to the new study, close examination of some of these wreaths located on the surface of Venus between it has relatively recent features, which means that they belong to modern volcanoes, and in turn indicates that Venus is geologically active.

Geological activity

Geological activity can be defined as the movement of tectonic plates beneath the surface of the planet, which means that its crust is divided into parts that move very slowly relative to each other.

In order for these plates to move, there must be a movement of heat between the planet’s inner layers. Evidence of this movement is the presence of volcanoes or earthquakes. As for the planets of Mars and Mercury, for example, they do not have this type of thermal movement in their interior, so they have no geological activity.

According to the new study, this is the first time that it was possible to refer to 37 places on the surface of Venus, the wreaths in which they were emerging. The study also indicates that they exist in the form of clusters in certain regions that appear to be more active than the surface of the planet.

Earth twin

The researchers hope that these new data will help to better guide the promising mission “Invision” to be launched in 2032, as “Invision” will be interested in building accurate radar maps of the planet’s geology and atmosphere, in an attempt to examine the extent of geological similarity between the planets of Earth and Venus.

Astronomers around the world refer to Venus as the “twin of the earth”, because they are roughly the same size, but it seems that it extends to something deeper than that, as they may have developed geologically in the same way as we do for the rest of the planets, which in turn raises many questions. .

Scientists believe that Venus was once as viable as Earth in its early period in its history, but with higher solar activity, water evaporated from its oceans and created its very dense atmosphere, making Venus the planet with the highest temperature in the solar system.
