The landform is shaped like the Earth’s largest satellite with Saturn’s largest satellite

Scientists said today that Saturn has many satellites, the largest one with large plains, sand dunes formed by ice-cold organic matter and liquid methane, which is the same as shaping the earth. Under the action, the surface has a chiseled mark.

A team led by Rosaly Lopes, a scientist at the California Institute of Technology, said the appearance of Saturn’s largest satellite Titan (also known as Titan) is “geologically visible in the solar system.” The most diverse.”

“The organic matter is vital to the possible life of the Titans,” said many of us, says Robes, a planetary geologist at the National Aeronautics and Space Administration (NASA)’s Jet Propulsion Laboratory. The liquid ocean under the icy ice-cold shell may develop life.”

Lopez added: “We believe that organic matter can penetrate down into the liquid ocean, and if life evolves, it will provide the nutrients needed to form life.”

In an article published in Nature Astronomy, scientists said: “Although the earth and the Titan’s material, temperature and gravity fields are different, many surface features are similar and can be interpreted as products of the same geological effect.”

Scientists say they use the radar and infrared data obtained by the Cassini spacecraft (Cassini) to fill many of the gaps in the map of Titan. The Cassini space probe crashed into Saturn after completing its 20-year mission in 2017.

They say that the sand dunes of the Titans are relatively young with the lakes, and the formation of the mountains seems to be earlier. The Titan is about 1.2 billion kilometers from the Earth.

Scientists say that the surface of the Titan is high or low under sediment accumulation and erosion. “With varying latitudes, there are distinct terrains, sand dunes in the equator, plains in the mid-latitudes, and twists and turns in the polar regions.” The area around the equator is very dry, and the closer to the polar regions, the higher the humidity.

Like Earth, Titan’s landscape is shaped by a variety of forces, including impact craters, liquid and air erosion, methane-containing rain, crustal plate movement and possible volcanic activity.

Alice Le Gall, a team member at Paris-Saclay University, said the Titan “is the only alien body known to have liquid on its surface.”

Legar told AFP that methane exists in three states: solid, liquid and gas in the ultra-low temperature state. Methane can make a cycle similar to the earth’s rain, forming rivers, lakes, and then evaporating into clouds.
