There are rivers, there are oceans, and the scenery is super earth-like One day in January 2005, the Huygens probe passed through Titan's thick orange clouds and transmitted pictures back to the mother ship Cassini. The images taken by Huygens reveal a surprising resemblance between Titan and Earth: rivers run down mountainsides and eventually flow from irregular coasts to oceans. The Huygens, built by the European Space Agency, landed on the cushions it carried. Since no one knows where the Huygens will land, whether it will be on solid ground or liquid, it is designed to land on soft surfaces, or even drift on liquids. When it landed and the camera looked around, it wasn't exactly an "alien world". The Huygens landed on a very smooth clearing with some Image Manipulation Service large pebbles, not real rocks, but rock-hard ice. The landing site looks like a delta on the earth. The gushing liquid forms these deposited pebbles. Because this terrain is hit and coalesced in the rapids, it appears to be quite smooth. In addition, when these flowing liquids enter the sea, they will look like It fell like a waterfall and tumbled and bubbled. These are the striking similarities to our planet. Except the temperature here is 180 degrees below freezing. 195-2 Photo Credit: Dais Culture It is more difficult to blow the wrinkled spring water on Titan than to go to the sky! Under the cloudy, orange dim sky, on the hard wood-textured mountainside, there was the sound of running water. Because it's so cold here, these sounds aren't coming from the flowing water we see here on Earth, but a lighter liquid. Instead of water, flowing on Titan is a mixture of liquid methane and ethane. In the solar system, only the earth can allow the three states of water to coexist. We have liquid water, solid ice, and water molecules floating in the air.

But on Titan, something else plays a similar role: methane and ethane. Some of the methane and ethane on this celestial body are in the form of solids, while others are in the form of gases or liquids. The water as we know it is cold enough to be as hard as steel in this place. On Titan, there are oceans and lakes formed from lighter liquids, methane and ethane. When these liquids evaporate, they reagglomerate to form rain and snow. The moon's weak gravity causes methane and ethane in the thick atmosphere to form huge snowflakes that slowly fall to the ground. Afterwards, some turn back to liquid, returning to lakes and oceans Image Manipulation Service along with rivers and creeks. Titan is a place other than Earth that has this complex "water cycle", but in fact it is another substance that replaces water. But the strange thing is that the ocean on Titan has no ripples. Radar images from Cassini showed that the oceans were almost smooth. On the 100-meter-wide surface of Lake Ontario (Ontario Lacus) in Titan's northern hemisphere, the undulating height is less than a few centimeters. This is believed to be because the liquid methane and ethane mixture is more viscous than water, and on this extremely cold planet, the winds are too weak to wrinkle the sea. Therefore, if you want to hold wind and wave sports on this satellite, you will definitely lose money. 195-2 Photo Credit: Dais Culture This satellite is most like Earth, but is there life? On November 12, 1980, when Voyager 1 flew into the Saturn system and aimed its camera at the massive moon, it got a mixed result. The reason for disappointment is that this huge moon is covered by a thick atmosphere and its surface cannot be seen; the happy place is that it is one of the few planets in the solar system with such a thick and mysterious atmosphere. A few large moons of the solar system have atmospheres, but the gas in these atmospheres is like a veil covering the surface. However, Titan's atmosphere is four times denser than Earth's, and the resulting atmospheric pressure is half that of Earth.
