Saturn defender "Titan" or keep "Jet" ice volcanoes.

<P> Keywords: pictures of Saturn and volcanic volcano eruption </ P> <P> world science and technology reports (tech.) YORK, Dec. 17, according to the British "Daily Mail" reported that, scientists say, Saturn .The largest moon - Titan, "Titan," ice volcanoes might live there, they will emit ammonia and methane, rather than lava. .</ P> <P align=center> </ P> <P align=center> Titan's ice volcanoes on the imagination of a graph </ P> <P align=center> </ P> <P align=center> .Titan Photo </ P> <P> from international cooperation project, "Cassini" spacecraft, radar images taken of view, the recent "Titanic" the surface of the liquid flow has occurred. .This finding shows that Titan may live ice volcano. ."Cassini" No radar team of scientists Luo Sali Lopez (Rosaly Lopes) said: "ice volcanoes in the solar system one of the most curious features. Figuratively speaking, if the volcano Mount Vesuvius in Italy is an ice .volcanoes, which emit the 'lava' will freeze the residents of Pompeii. "</ P> <P> University of Arizona," Cassini "mission scientists 乔纳森卢尼 No. Le (Jonathan Lunine) said .The latest data show that the ice volcano is not only the geological periods in the past the "Titanic" had appeared, now may still be present in the satellite above. .Landing in 2005, the surface of Titan, "Huygens" spacecraft showed that Titan was once ice volcano "come and go." .</ P> <P> "Titan" small solar system objects in the atmosphere has important one. .Scientists believe methane gas in the atmosphere to form clouds and eventually spread to the "rain" on the form of landing on the surface, but the source of methane is still a mystery. .Theory of ice volcanoes, scientists tend to think that, from the "Titan" internal jet of methane could explain why this satellite has a smoky atmosphere. ."Cassini" No. spectrometer data obtained showed that the "Titan," the two regions appear bright spot. .In one area, the scientists found evidence of the existence of ammonia frost, they think that ammonia should come from the "Titan" internal. .</ P> <P> the observations found in the American Geophysical Union meeting in San Francisco announced, but not all participants believed this evidence. .NASA Ames Research Center planetary scientist Jeff Moore (Jeff Moore) said, observing that although very attractive, but the lack of decisive. ."Indeed there are some things happen, but what is unclear." Since 2004, "Cassini" sign has been around the orbit of Saturn, its rings and satellite research. .</ P> <P> 16 days, NASA announced the "Cassini" was found in Enceladus, "Enceladus" is evidence of the formation of the crust. .This process has occurred on Earth similar to the process - and the outward expansion of the surface crack, the formation of the crust increases the possibility of underground ocean of liquid water exist. ."Cassini" No Imaging Team Leader Carolyn Ball Division (Carolyn Porco) in the BBC interview, said: "We grasp the existence of liquid water on Enceladus the evidence is a little bit more." < ./ P> <P> Enceladus new crust is formed like a tiger stripe cracks, these cracks and split the earth cracks in mid-ocean ridges similar. .Has participated in this project, Dr. Paul Roch Alphen Cornell University Stan (Paul Helfenstein) said: "We see on Enceladus, a type of surface crack propagation, this expansion is very asymmetric, as is .a conveyor belt. If the well flow from a hypothesis, this expansion can only advance in one direction. on earth can this phenomenon, but in very special conditions.
