Scientists have performed a new analysis of the surface of Venus which revealed evidence of tectonic movement. This evidence is in the form of crustal blocks that have blocked against each other like pieces of broken pack of ice on the lakes and oceans of the earth. The researchers say that the movement of these blocks could indicate that Venus is geologically active and gives information on tectonia exoplanet and an early tectonic activity on Earth.
The researcher Paul Byrne says that the research team has identified previously unrecognized models of tectonic deformation on the surface of Venus. Byrne says that the pattern indicates that it could be driven by the interior movement, just as tectonia is on earth. However, the researcher is clear that the view on Venus view is different from the tectonics observed on the Earth.
Despite the differences, the conclusion is the proof of the internal movement in Venus expressed on the surface of the planet. It is an important discovery that astronomers assumed that Venus consisted of a solid external hull still, like Mars or the Moon for a long time. The earth is clearly different from these other celestial bodies because its lithosphere is broken into tectonic plates that slide against, away from, and under each other.
The researchers used radar images of the mission of NASA Magellan to see the surface of Venus. The team led a detailed examination of the lowlands on the planet that make up most of its surface areas and noticed where large blocks of the lithosphere seem to have moved as a broken pack ice on a frozen lake here on earth.
The researchers then created a computer model of the deformation and found that the slow movement of the interior of the planet could explain the tectonic they saw. Byrne says that the observations tell the team that the inner movement leads to surface deformation on Venus in a method similar to that of the Earth. However, the team is clear that they do not see the tectonics of plates as we have on the earth, but what they see are evidence of deformation due to an inner coat flow on Venus. This means that Venus can still be geologically active.
