NASA scientists have unveiled the fact that the methane lakes on the surface of Saturn, Titan, are the only place in the solar system other than the Earth with a liquid on the surface.
The old theory suggested that Titan's surface lakes, dubbed "Earth-like", were formed by liquid methane that dissolves the rocks below, forming these lakes in what looks like terrestrial karst lakes, but the study of new data from the Cassini spacecraft, namely A mission conducted by NASA's reaction propulsion laboratory in Pasadena, California, provided a new scenario to explain why some methane-filled lakes are surrounded by very high peaks, several hundred feet high.
The new theory says that pockets of liquid nitrogen in Titan's hot crust turn into explosive gas, explode in the hole and then fill it with liquid methane.
This explains the appearance of smaller lakes near the north pole of the Saturn moon, similar to those of Winnipeg Lacos, which appear in radar imagery with steep edges and an altitude higher than sea level.
Scientists have struggled to explain these edges with the previous theory that drilling is created by a flow of fluid, supposed to create smoother edges, so they are short and flat.
The international team of scientists led by Giuseppe Miter, University of Gi d'Annunzio, revealed that she found no explanation for the sharp edges rather than the softened edges adapting to the edges of karst lakes, where the training was more compatible with the blowing nozzle, which supports The edge is formed by the extruded material from the inside of the hole, ie it is about 39, a completely different process.
The Cassini Mission is a NASA collaborative project with the European Space Agency and the Italian Space Agency aimed at studying Saturn and its system, including its rings and moons.
