Ice Mountain at Saturn Satelit

For the first time, scientists now have strong evidence of the existence of the iceberg on Titan, Saturn's largest moon. Thus the results of a recent study released Tuesday (14/12).As usual lava, this mountain can spew water ice, hydrocarbons or any other material to Titan's thick atmosphere.The existence of such iceberg could help solve some mysteries about Titan's carbon cycle. This can increase the likelihood that there is life on the giant moon."We finally have some evidence that Titan is a world that is active," said Randy Kirk, a U.S. geophysicist in Flagstaff, Arizona, on Tuesday (14/12).Many scientists think the iceberg is also known as cryovolcanoes, perhaps similar to the cold months of the outer solar system.Previous studies have offered evidence that Titan, Saturn's largest moon, may be a cryovolcano port as well. These new findings into evidence the presence of the iceberg for the first time.Kirk and his colleagues used observations made by NASA's Cassini spacecraft in orbit around Saturn. Using radar with visual and infrared mapping spectrometer instrument show. Cassini took detailed images of Titan's area known as Sotra Facula.These photos capture three images with a big cone of material flowing from the iceberg. In addition, also appeared several holes.Tip of the iceberg is estimated height of about 3280 to 4921 feet (1,000 to 1,500 meters). One hole has a depth of about 4921 feet (1,500 meters).Overall, these land forms leads to an iceberg or cryovolcano."This is really a combination of features that make us think we have found good evidence of a mountain on Titan," said Kirk.Theoretically, a deep hole would be a crater. But the theory is disputed by other researchers."Very rarely have craters on Titan," said Jeffrey Kargel of the University of Arizona, who was not involved in new research. "But Cryovolcanism is the best explanation, in my view."
