Before Cassini's Saturn's spacecraft went down into Saturn's abyss, it made the final 2017 flyby of Titan, Saturn's largest moon. This remote world is the only place in the solar system except Earth that hosts large bodies of standing fluid. The Titan fluid is methane and ethane rather than water. But these lakes and marches make the moon one of the most interesting places in our solar system.
Cassini's last trip to Saturn's moon revealed that some of its northern lakes are 300 feet deep, but small over the area and considered to be atop high hill. The shape and location of the lakes strongly indicate that the lakes are similar to the karstic lakes on Earth, where the liquid eats and eventually falls around it. On Earth, it occurs in water and limestone, but in Titan, it is fluid methane and the organic organic materials that make up the layers of Titan. Researchers published their search on April 1
In a second study, published in Nature Astronomy various research teams discovered what they called "phantom lakes" The surface of the Titan in the northern hemisphere . These lakes appear in earlier Cassini data and disappear later. Scientists have taken it to say that the lakes are shallow, and dry and lose while the Titan weather changes. A full-time period in Titan is almost a Saturnian orbit, or 30 Earth years. And since Cassini has studied 13 years of studying the Saturn system, it has a great point to watch the northern hemisphere grow hotter in the beginning of summer, while the southern hemisphere falls in the winter.

These two studies refer to the complex of Titan's methane cycles that scientists are still looking for. Like the Earth's water cycle, the fluid moves between the Titan's atmospheric, surface, and underground, and changes in weather and temperature. It is the only place except Earth where scientists can watch the complex cycle of fluid on a planet in full scale, and they will certainly keep Cassini data mining until the time comes for Saturn to host a new visitor spacecraft.
