If Titan were composed entirely of stiff rock, the gravitational attraction of Saturn should cause bulges, or solid "tides," on the moon only 3 feet (1 meter) in height. Cameron backs ‘real-life Avatar’ space project, Hyper-slow sea microbes give hope for life on Mars, Not Pluto: Mercury Mickey Mouse snapped by NASA orbiter. The network also supports selected Earth-orbiting missions. Cassini’s measurements revealed that Titan actually bulges a substantial 30 feet, indicating that the moon’s surface rides on top of a sloshing layer of water of unknown depth. Read RT Privacy policy to find out more. The lack of liquid water on Titan's surface was cited by NASA astrobiologistAndrew Pohorille in 2009 as an argument against life there. “I am intrigued by how many features on Titan’s surface are remarkably Earth-like,” Spilker said, “including hydrocarbon rivers, lakes and seas, and equatorial dunes, with liquid methane playing the role on Titan that water plays on Earth.” Although there are liquid hydrocarbon lakes on Titan, at temperatures that low the phospholipid tails would also become far too rigid and stiff to form a flexible membrane. There are other planets in the Solar System that presumably have water deposits under layers of ice and where microbial life might be found. The results have a bigger implication for the mystery of methane replenishment on Titan. Categories: Feature Stories Titan. What are the characteristics of the Solar System? The finding appears in today's edition of the journal Science. There is water, but not very much. Scientists think life is more likely to arise when liquid water is in contact with rock, and these measurements cannot tell whether the ocean bottom is made up of rock or ice. Unfortunately, rather than a water cycle, Titan … The variety of features on Titan’s surface has surprised and delighted scientists and the public alike.

Pohorille considers that water is important not only as the solvent used by "the only life we know" but also because its chemical properties are "uniquely suited to promote self-organization of organic matter". This artist's concept shows a possible scenario for the internal structure of Titan, as suggested by data from NASA's Cassini spacecraft. At first, scientists were not sure Cassini would be able to detect the bulges caused by Saturn's pull on Titan. Determining, however, whether there actually is water on Titan will remain for quite a time, as there are currently no means to drill through 100 kilometers of moon ice. Titan is the largest moon of Saturn and the second-largest natural satellite in the Solar System. -- An international team of scientists, including a University of Waterloo chemistry professor, has conclusively demonstrated that water (actually steam) does exist on the sun, confirming a breakthrough finding made two years ago. Titan has thick crust of water ice and scientists think that there is even liquid water underneath it. Titan has a dense atmosphere of 95 percent nitrogen and 5 … For more information about Cassini's mission to Saturn, visit: http://www.nasa.gov/cassini and http://saturn.jpl.nasa.gov . The gravitational pulling by the sun and moon also causes Earth's crust to bulge in solid tides of about 20 inches (50 centimeters). They are used to fight in the Dungeon, Guild Wars, and the Tournament of the Elements. In the open oceans, those can be as high as two feet (60 centimeters). A liquid layer between the external, deformable shell and a solid mantle would enable Titan to bulge and compress as it orbits Saturn. The evidence is tidal. This suggests Titan is not made entirely of solid rocky material.

Scientists say large deposits of water drastically increase the possibility of life on the moon. The liquid that fills Titan's lakes and rivers is not water, but liquid methane, probably mixed with other substances like liquid ethane, all of which are gases here on Earth. "Cassini's detection of large tides on Titan leads to the almost inescapable conclusion that there is a hidden ocean at depth," said Luciano Iess, the paper's lead author and a Cassini team member at the Sapienza University of Rome, Italy. Methane is abundant in Titan's atmosphere, yet researchers believe the methane is unstable, so there must be a supply to maintain its abundance. The NASA/European Space Agency Huygens probe, which landed on Titan’s surface on January 14th, 2005, studied the moon’s atmosphere as it descended. The question of how much liquid is on the surface is an important one because methane is a strong greenhouse gas on Titan as well as on Earth, but there is much more of it on Titan. This finding supports the idea that Titan has a "hydrological cycle" as does Earth, but instead of water (forming clouds, raining out and evaporating into clouds again), there … If Titan were a solid body, it would barely be affected, bulging only about 3 feet during its closest approach to Saturn. © Autonomous Nonprofit Organization “TV-Novosti”, 2005–2020. Cassini succeeded, however, by measuring Titan's gravitational field during six close flybys from Feb. 27, 2006, to Feb. 18, 2011. Scientists explain mysteries of the “methane cycle” on Titan – a cousin to Earth’s water cycle. The presence of a subsurface layer of liquid water at Titan is not by itself an indicator for life. Yes of course there is a water on titanic Titan tankless water heaters can be purchased online at Tank the Tank, Hot Water, Local, Amazon, eBay, Titan, Titan Water Heaters, and Tankless Water Heaters. June 28, 2012: Data from NASA's Cassini spacecraft have revealed Saturn's moon Titan likely harbors a layer of liquid water under its ice shell. They can be leveled up with Titan Potions or Emeralds, evolved with Titan Soul Stones and be equipped with Titan Artifacts. All rights reserved. A liquid water ocean, "salted" with ammonia, could produce buoyant ammonia-water liquids that bubble up through the crust and liberate methane from the ice. However, his claims go against t… How do Earth, the planets, and the heliosphere respond? Such an ocean could serve also as a deep reservoir for storing methane. June 28, 2012: Data from NASA's Cassini spacecraft have revealed Saturn's moon Titan likely harbors a layer of liquid water under its ice shell. Water on the Sun?.
