Whether Venus, one of the Solar Systems 4 terrestrial planets, ever had oceans stays an unsolved puzzle. Although an American research study assumed that it did, this is now challenged in a paper published just recently in Nature, involving in specific researchers from the CNRS and University of Versailles-Saint Quentin-en-Yvelines [ 1] (UVSQ). Using a cutting edge climate design, the research group has actually developed an alternative circumstance to the American study.

Soon after its birth 4.5 billion years ago, the young Venus was covered with magma. Such a fall in temperature level would just have actually been possible if the surface of Venus had been protected from solar radiation by clouds.
The scientists environment model, nevertheless, revealed that clouds would have preferentially formed on the night side of Venus, where they could not protect the surface from sunlight since that side gets none. On the contrary, rather of acting as a shield, the clouds helped keep high temperature levels by causing a greenhouse effect that caught heat in the worlds dense atmosphere.

Such a fall in temperature level would just have been possible if the surface area of Venus had been shielded from solar radiation by clouds.
According to this climate design, the high surface area temperature levels prevented any rains, and, as a result, the oceans were never ever able to form.

In France, researchers from the Laboratoire dastrophysique de Bordeaux (LAB) (CNRS/ University of Bordeaux) and the Laboratoire” atmosphère et observations spatiales” (LATMOS) (IPSL, CNRS/ University Versailles St Quentin/ Sorbonne University) took part in this work. The study was led by the University of Geneva, Switzerland.
The goal of the Envision mission prepared for 2030 in addition to the Davinci and Veritas missions set up for 2029 is to study Venus.
