Neal found on Titan

14/12/2012

Just did earthly landscapes and then photographs the U.S. Space probe Cassini, located near Saturn. At the North Pole of Titan — a satellite of the planet, almost the size of our moon, scientists have spotted many large lakes connected by channels. Surface of some stretches for more than a hundred kilometers. The terrain is very reminiscent of Karelia, Finland or Canada.

Near the south pole of Titan probe photographed the lake, named Ontario. A planetary scientists led by Thomas Cornet of the University of Nantes spotted it similar to the terrestrial salt lake Etosha Pan, located in Namibia. They are not just similar in appearance. Both in the same way that filled by the rain, then dry it evaporates.

The other day, NASA announced the new images taken by the probe. They see the river: a copy of the earthly Nile. Although it is a little shorter.

— Titan — the only object in the solar system
— after the Earth, of course, the surface of which is always something flowing, — says one of the principal investigators Jonathan Lunayn the University of Arizona.

But what's flowing? Because Saturn is the world "shifted temperature" on our 100, and places and to 200 degrees in the negative. Real kingdom "Snow Queen." Therefore, in the rivers and lakes — not water.

— On Titan flowing liquid hydrocarbons — a mixture of methane, ethane, propane, — explains the scientist. — They're filled with rivers and lakes, and the local sea. Local Nile, for example, falls into the sea Kraken (Kraken Mare), which is greater than the Caspian, but less than the Mediterranean.

Recently been refined: a liquid titanium nearly 80 percent ethane, about 10 percent methane and about 8 — propane. The rest — butene, butane and acetylene. What is also liquefied natural gas. It seems focused on Titan largest in the solar system and its reserves. Such that no Gazprom never dreamed of. But where did they come from is not known.

Scientists have repeatedly stressed: Titan resemblance to Earth's awesome. In fact, besides the continents, seas, rivers and lakes in the satellite has an atmosphere, clouds, fog. There are rains. The weather changes. And the cycle of liquid similar to Earth. And even discovered molecules that resemble amino acids from which proteins are constructed of terrestrial organisms. But is there life on Titan?

Biologists answered evasively: we do not know yet being able to metabolize at a temperature of minus 180 degrees Celsius.

REFERENCE "KP"

He is the only one

Titan — the largest moon of Saturn. Among the satellites in the solar system is inferior in size only Ganymede — satellite of Jupiter. Titan — larger than Mercury. And almost twice as heavy as our Moon. Located on Saturn is about 3 times farther from Earth than the Moon. Therefore looks at the sky saturianskom drive half moon.

Titan — the only moon in the solar system that has a dense atmosphere.

The mission of the probe Cassini, which NASA cooperates with the European Space Agency and the Italian Space Agency, extended until 2017. It will end up that the probe will be sent straight to Saturn. Before the break, he has to send data about the atmosphere of a giant planet. Maybe something will be able to take a picture.
