USA.- Venus is still under investigation and recently it was believed dead due to its toxic atmosphere and the high temperatures it has. But new research from NASA has revealed that this planet is geologically active. For this reason, it had been assumed that it had a stationary lithosphere (a solid outer layer), very similar to that of Mars and the Moon. NASA’s Magellan mission was responsible for broadcasting a series of images captured in the 1990s that reveal the existence of movements on this planet. “Hemos identificado un patrón de deformación tectónica no reconocido previamente en Venus, uno que es impulsado por el movimiento interior al igual que en la Tierra”, expresó Paul Byrne, author principal del estudio y profesor asociado de ciencia planetaria in the Universidad Estatal de Carolina North. In this sense, it has been explained that everything indicates that these are blocks of crust that have moved “against each other”, which may be similar to what happens with ice in polar seas. . It is therefore the Magellan probe that was able to take pictures of the lowlands of Venus which constitutes most of the surface. And the images captured that the lithosphere could have had movement.

For their part, the researchers assure that it is an internal movement of Venus, which opens the possibility of refuting the theory according to which the planet was dead. “These observations tell us that inner movement causes a deformation of the surface of Venus, similar to what happens on Earth,” Byrne pointed out. The expert clarified that what happened could be similar to what is happening on the Earth’s surface due to the activity inside. Plate tectonics on Earth are driven by convection in the mantle. The mantle is hot or cold in different places, it moves, and part of this movement is transferred to the Earth’s surface in the form of plate movement. A variation of this process also appears to occur on Venus, ”he said.
