And how to act and exotic and unpleasant, Titan ruled temperature of minus 179 degrees Celsius, like the similar planet Earth in the solar system. Unlike the water system of the country are the main components of coal hydrogen, methane and ethane.
One of the most spectacular discoveries of the probe of NASA are the magical islands in the great northern lakes on Titan that footage ever appear and sometimes they will not. Astronomers have not been able to explain this phenomenon, because on reflection surface lakes can not be inferred from that comprise or because they are sometimes present and sometimes not.
A team of scientists gathered around Michael Malask the laboratory of NASA’s jet propulsion think the mystery is solved: they assume that it is not about to become icy hydrocarbons, as far assumed but large areas of gas bubbles. They came to this conclusion based on new data collected by the Cassini probe.
Laboratory experiments have shown that when a combination of different blends of coal hydrogen eg heavy rain or river inflow into the river, sometimes comes to the release of large amounts of nitrogen and foaming. Temperature change in depth can also lead to the creation of etan ice and later to release bubbles of gas.
On the basis of research at NASA, they are sure that the lakes on Titan may appear in areas subject to bubbles and more often than you might anticipate.
For about a month the new measurement probe Cassini can confirm this thesis of causing magical islands.
Freezing Fizz and Breathing Lakes
In characterizing how nitrogen moves between Titan’s liquid reservoirs and its atmosphere, the researchers also coaxed nitrogen out of a simulated ethane-rich solution as the ethane froze to the bottom of their tiny, simulated Titan lake. Unlike water, which is less dense in its solid form than its liquid form, ethane ice would form on the bottom of Titan’s frigid pools. As the ethane crystalizes into ice, there’s no room for the dissolved nitrogen gas, and it comes fizzing out.

While the thought of hydrocarbon lakes bubbling with nitrogen on an alien moon is dramatic, Malaska points out that the movement of nitrogen on Titan doesn’t just move in one direction. Clearly, it has to get into the methane and ethane before it can get out.
“In effect, it’s as though the lakes of Titan breathe nitrogen,” Malaska said. “As they cool, they can absorb more of the gas, ‘inhaling.’ And as they warm, the liquid’s capacity is reduced, so they ‘exhale.'”
A similar phenomenon occurs on Earth with carbon dioxide absorption by our planet’s oceans.
Results of the study were published online in February by the journal Icarus.
