When you think about a month, you can think of a rocky, crater-filled wasteland with a lot to do, as well as wandering around on your ride. Although the Earth's moon is certainly the essence of a dead world, there are more than 200 months in our solar system orbiting planets and asteroids. The universe, which is lucky for human scientists, is very creative to make all the moons as static as we are.
Using recently analyzed data from NASA's Cassini mission, astronomers published a study of a new map of the surface of Saturn's largest moon Titan this week. The first map of its kind reveals a world similar to Earth – especially the Titan is full of mountains, plains, valleys, craters and lakes. This is unlike any other place in the solar system except Earth. Surprisingly, even the atmosphere of Titan looks like Earth's atmosphere in its old days.
“Titan has an active methane-based hydrological cycle that creates a complex geological landscape that makes its surface one of the most geologically diverse areas in the Solar System ları. Rağmen Despite differences in material, temperature and gravitational fields between Earth and Titan, most surface properties are similar and can be interpreted as products of the same geological processes. ”
Although researchers have an idea of the different areas of the month, the new analysis and the map revealed some surprises.
Im I'm a little surprised that the plains are more Titan than I thought, Ros said Rosaly Lopes, co-author of the planetary scientist and research at NASA's Jet Propulsion Laboratory in Pasadena, California.
Specifically, the map reveals that two-thirds of the moon's surface is flat plains, 17 percent sand dunes, 14 percent hills or mountains, and 1.5 percent valleys. A little over one percent of its surface is filled with liquid, but unlike Earth, the liquids are liquid methane, not water.
“Titan has winds, rains, lakes, seas, rivers to make common plains, so it's a really different moon from the usual crater surface you see,” he said.
Titan's diversity and similarities to the world make the moon a place where microbial life can be found.
Biri One of the places like the solar system[ly] Lopes said that life may have changed, because we have a combination of many organic substances. Opes
Unfortunately, we'll probably have to wait two more years to find out. NASA plans to send a plane to Titan in Dragonfly mission in 2034, which flies over the surface and examines the bear in detail. Because the Titan has a slightly thicker atmosphere than Earth and there are cold but not cold temperatures, a rotor-based drone can easily strike around a live moon.
In the meantime, if we go back to Earth, researchers will consider not only the diversity of the moon, but also the locations of various formations. Most of the lunar methane lakes may be the result of the elliptical orbit around Saturn, which leads to longer summers in the northern hemisphere and the southern hemisphere in the northern hemisphere.
Tracy Gregg, a planet geologist at the University of Buffalo in New York, told Nature that this map will help researchers answer important questions about the Titan. “First: What seasonal changes have Titan gone through and what kind of changes can there be? [heat] Titan? "says.
Lopes said Titan would be considered a planet on its own if it was not parked in orbit around Saturn.
“Titan is a very different moon, a very different world, and if it is not orbiting around Saturn, we can say that it is a planet because it has the second most dense atmosphere as a solid structure in the solar system. Venus is first, Titan, second, Earth, third. ”
Erken As I study Titan further, I think we can learn more about what led to the evolution of a very different moon, ”he added.
