Eighteen mysterious Titan spacecraft like a UFO

          They look more like a flying saucer, not the icy satellites, Titan Titaneighth and fifth is the most unusual satellite of Saturn. Scientists have long questioned the two satellites of the outer disc shape ishow to form, their diameter is only 32 miles. Currently, researchersfrom the European Space Agency after several years of the universe obtained image analysis revealed an important clue to its mystery
          They found that the quality of Saturn's smaller satellites 14 very low-density, half of the satellite is ice structures, their appearance suggests they arise from the ring. However, these satellites require a "jump start" does not exist here, so that small particles into the ring fusion of gravity. Therefore, each satellite in the form of supermassive core, which is leading the formation of the original collision ring residue.

    Caroline, the European Space Agency - Boer Ke (Carolyn Porco) said: "We think that these 'flying saucer' shaped satellite with a peculiar shape structure, is initially less porous ring particles with a large mass core, these particles together is easy. "In this process, the satellite will gradually increase the volume, even if it is in close proximity to Saturn. Will eventually form a dense ice core is two to three times the size of the ring structure, it is covered with a thick layer of porous material layer of ice ring.

    2010, Southwest Research Institute, a computer simulation suggests that the first Saturn Titan has several like the larger size of the satellite, the early formation of their spiral of Saturn with Saturn together. When the satellite is close to Saturn by Saturn's gravitational effect of shape can be flexible and heat generated, so that part of the satellite's ice melt, rock deposited in the central region of the satellite. Meanwhile, the planetary tidal forces can strip the outer layer of the material of satellite form the initial structure of the ice ring.

    Southwest Research Institute of Planetary Science Council, Robin - Camp (Robin Canup) study led by Dr., he said: "This new computer simulation shows that the satellite as the flying saucer is the original ecology of the ring, Saturn's largest satellite earth Titan formed in the same period. This implies that the ring structure of these satellites and satellite there are internal links, including the formation of Tethys are also similarities, and that they are companion satellite Titan debris body.

    But how to explain Titan Titan eighth and fifth ridge-like structure with a peculiar and unique shape it? Scientists think the answer in the accretion disk, they are found in space, from the protoplanetary disk to the galaxy. In essence, with the accretion disk rotation, the force will lead to flat edges of the satellite, and toward the central region of expansion.

    The University of Paris VII, France Sebastian - Charles MozTW (Sebastien Charnoz) said: "Our computer simulations show that the ridge-like structure protruding should be rapid growth, when Saturn's rings are very thin, eighth in the Titan and near the equator, forming Titan fifth smaller accretion disk.
