Resolved Question: Would a high technology like that of space aliens make possible the colonization of Titan, the Saturn's moon?

The conditions on Titan: "Titan is the largest moon of Saturn, the only natural satellite known to have a dense atmosphere and the only object other than Earth for which clear evidence of stable bodies of surface liquid has been found. The number of methane lakes visible near Titan's southern pole is decidedly smaller than the number observed near the north pole. As the south pole is currently in summer and the north in winter, an emerging hypothesis is that methane rains onto the poles in winter and evaporates in summer In June 2008, the Visual and Infrared Mapping Spectrometer on Cassini confirmed the presence of liquid ethane beyond doubt in Ontario Lacus The atmosphere of Titan is largely composed of nitrogen, and its climate includes methane and ethane clouds. The climate—including wind and rain—creates surface features that are similar to those on Earth, such as sand dunes and shorelines, and, like Earth, is dominated by seasonal weather patterns. Researchers have suggested a possible underground liquid ocean might serve as a biotic environment. Titan's surface temperature is about 94 K (−179 °C, or −290 °F). At this temperature water ice does not sublimate or evaporate, so the atmosphere is nearly free of water vapor. The findings of the Huygens probe indicate that Titan's atmosphere periodically rains liquid methane and other organic compounds onto the moon's surface." Would a high technology like that of extraterrestrial intelligent life forms(if they exist) make possible building a city on Titan protected by layers and equipment which isolates it from the hostile to life conditions on Titan (poisonous rain and temperature) and make possible living on the surface of Titan? Remember that all this is theoretical.YES or NO? Can aliens colonize it? more

That the END of the world is this coming 2012, have you ever remember PLANET NIBIRU that will collide with EARTH and surely all of us will DIE no one survive thats why US is trying to search MARS beacuse all of the richiest person can transfer there. BUT HOW BOUT THOSE POOR PEOPLE CANT AFFORD TO TRAVEL IN SPACE. THE PROOF: http://www.maya12-21-2012.com/nibiru.html Saturday March 29, 2008 9:45p, EST BRISBANE, Australia - Our series on the phenomena created by the possibility that there is indeed a planet X has generated a lot of response. Researcher, Cristian Negureanu, sent this explanation for the interest in Planet X or Nibiru. The real cause of climate changes, volcanoes activity, intensification of the seismic activity etc., is the planet Eris’s getting closer to our solar system, intermediary named 2003 – UB – 313, and known in Antiquity under various names as: Nibiru, Marduk, Nemesis, Hercolubus, the Gods Planet, the Planet of the Empire, the Planet of the Cross or the Red Planet. Below is a short record of the first (recent) contacts with Eris: First observed on October 21, 2003 using the 1.22 Oschin telescope, at Mount Palomar Observatory ( California ). Discovered by Michael E. Brown, Chad Trujillo, David L. Rabinovitz, on January 5, 2005, based on the photos taken at the above mentioned date. Furter observations published in October 2005 have shown a satellite named Dysnomia (Gabriel). The planet Eris/ Nibiru periodically getting closer to Earth once in 3,600 years generates numerous climate changes, one being the global warming with its natural consequence – the melting of the glaciers. The effect of glaciers melting, because of their sweet water, will be the ending of the thermo – saline natural system, the “ engine “ that allows the Gulfstream circulation to the North and the freezing of spread areas in the North – West of Europe and North – East U.S.A. Briefly, here is the process that took place during the last two periods in which the Gods planet has passed between Mars and Jupiter, the nearest point to Earth: 7,200 years ago, during the cataclysm known as “Noah’s flood“, “sudden changes in temperature, violent storms and water avalanches from Antarctica broke off from their ‘ice prison’ Dr. John T. Hollin at Maine University (U.S.A.) considers that large pieces periodically came out of the Antarctic ice field creating a huge tide” (Zecharia Sitchin, The Twelfth Planet). 3,600 years ago, during the Jews’ Exodus from Egypt in the middle of the second millennium B.C., the Earth suffered big cataclysms. “A celestial body that recently entered our solar system – a new comet – came very close to Earth [causing – A/N] the eventual disappearance of the glacier layer“ (Immanuel Velikovsky, “Worlds in Collision“). The current situation – the Poles glaciers’ melting is accelerating . The climate and geological changes will increase because the planet Eris/ Nibiru has not even been close to Pluto, its nearest point to Earth. This is supposed to happen between 2012 – 2014. Nowadays, identical phenomena (global warming and volcanoes activation) also take place on other planets from our solar system because of Eris/ Nibiru. Here are few examples: The Neptune’s moon, Triton is warming (BBC Science & Technology News, July 25, 1999). Pluto experiences an extraordinary heating (Massachusetts Institute of Technology News, October 9, 2002). Volcanic eruption on Jupiter’s satellite Io (Icarus Astronomy , November 2002). The warming of Mars (ABC News, December 7, 2002). The warming of Saturn (January 28, 2007, www.interstars.net): scientist of the UCLA (University of California, Los Angeles) – physics and astronomy department and those at the University of Boston have noticed that the temperature of the superior atmosphere of Saturn is higher that estimated. Thus, professor Allan Aylward at UCLA considers necessary the reexamination of the main hypotheses regarding the planetary atmosphere and establishing the cause of the respective heating. He also noticed a similar process on Mars, concluding: “Studying the aspects within other planetary atmospheres will help us to find out clues of the Terra’s future“. The books already mentioned also include various other description of severe phenomena as volcanoes activation, increasing seismic activity, terible hurricanes, huge tides, Pole reversal, and so on, that happened 7,200 years ago, respectively 3,600 years ago, processes that are more and more frequent nowadays on Earth. Here are few additional arguments that Eris is Nibiru: The number of its satellites. Zecharia Sitchin said on them in the above – mentioned work : “Four satellites [they had a rapid rotation movement,‘swirling like twirls’ , three other satellites – The Mad Wind , The Twirling Wind and The Sovereign Wind, using their satellites as ‘assault chariots’, he (Nibiru – A/N) sent ahead the winds, the all seven winds ready t more

Resolved Question: Can you explain to me this but just shorter ?

LAUREL, MD. — Ask planetary scientist Mark Sykes where NASA’s Dawn spacecraft is headed, and he will say it is on its way to the largest asteroid and the smallest planet. Dawn launched in September 2007 and is scheduled to rendezvous with the asteroid Vesta in 2011 and then with the dwarf planet Ceres in 2015. But a dwarf planet is not a planet — at least that is what the International Astronomical Union declared in 2006. Technically, Sykes’ comment is incorrect. But Ceres is a planet, “my favorite planet,” Sykes said August 14 during the Great Planet Debate Conference held at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md. Sykes, who is director of the Planetary Science Institute headquartered in Tucson, Ariz., is one of many scientists calling for a definition of the word “planet” other than the IAU definition. A planet in the solar system, the IAU says, must: orbit the sun; have enough gravity to make it nearly round; and have gobbled up or sent packing any objects found in its orbit. A dwarf planet, under IAU rules, is not a planet. The IAU says a dwarf planet orbits the sun, is not a satellite, has enough mass to make itself nearly round and has not booted objects from its orbit. But how can a dwarf of something not be considered one of that thing? Sykes asked. That sentiment was expressed again and again by many scientists at the conference. “It is grammatically and logically weird that a dwarf planet is not a planet. That rule is unacceptable and violates laws of logic and grammar,” said planetary scientist David Morrison of the NASA Ames Research Center in Moffett Field, Calif. The IAU definition of planet pleases no one, which is ironic because words are to be useful and easy to understand, he said. So during the conference, Morrison called for the withdrawal of the IAU definition, an action he said would be unlikely. He then suggested that the IAU definition be ignored. And that is what Sykes is doing, he said — at least partially. He is selecting the part of the IAU definition that he finds useful, arguing that a planet is anything that orbits a star, doesn’t fuse elements in its core and has enough internal gravity to be nearly round. Those criteria would make Ceres a planet. It would remake Pluto one too. There would be at least 13 planets in the solar system with many more, possibly thousands to come, he said. The thousands would lie in the Kuiper Belt, the ring of planet-like chunks of rock and ice in Pluto’s neighborhood. Not all conference attendees agreed, though. “It is easier to determine if a larger object is dynamically dominant, meaning it dominates the orbit, not necessarily clears it, compared to determining whether a smaller object is round,” said astrophysicist Steven Soter of the American Museum of Natural History in New York City. He did note that he was not advancing the IAU’s definition, but rather was suggesting that using dynamics to define objects is more straightforward than defining a planet based on its gravity establishing its roundness. That in essence means the planet's internal gravity is strong enough to make the object nearly round. Labeling planets based on their dynamics around the sun distinguishes the planets as Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. But if Earth were orbiting the sun out in the Kuiper Belt, based on a dynamical definition and the mass of Earth, it would not be a planet, Sykes and other scientists pointed out. “The dynamics perspective misses the point of planet classification,” which is to group like things together, said planetary scientist Alan Stern of NASA’s science mission directorate based in Washington D.C. And, “it ignores the 300-plus planets found outside the solar system,” he added. “A definition based on the physical, the intrinsic properties of a planet does not,” he noted. Such a definition might seem to add confusion because it would include a planet’s moons as planets too, Stern said. “But we are just going to have to get over that,” he said, because what makes a broad, physical-based definition of a planet useful is that it allows scientists and educators to “put like things together in the same bin,” and then make sub-bins or subcategories of planets such as satellite planets, dwarf planets and extrasolar planets, he explained. Those subcategories could be added to already existing categories, such as terrestrial planets, gas planets, rocky planets, inner planets and outer planets. But making moons and others objects planets is a “radical step” away from the definition of planets as the public knows it, Morrison said. And since “planet” is a cultural term, it is dangerous to change the term to that extent, he argued. Stern countered by saying that his concept of a definition — one “based on the physical, the intrinsic properties of a planet” — is how he defines a planet. It also pushes the bounds of what a planet is. When, or if, more

Saturn is known as the sixth planet from the sun. It is also the second largest planet in the solar system, right after Jupiter. Saturn is also known for its rings, they consist mostly of ice particles. Sixty known moons orbit Saturn. Titan is Saturn’s largest moon. Titan is also the second largest moon, right after Jupiter’s moon. It is also bigger than the planet Mercury. Saturn is about ninety-five times the mass of earth. Saturn is the only planet in the solar system that is denser than water. Due to a combination of its lower density, rapid rotation, and fluid state, Saturn is an oblate spheroid, which is flattened at the top of the poles and bulges at the equator. There is little known about Saturn’s interior. Saturn has a small rocky core surrounded mostly by hydrogen and helium. The core region is about 23 times the mass of earth. Saturn’s interior can reach 11,700 degrees Celsius, that’s hot! Saturn’s core is similar to earth’s but denser. As deeper and deeper in the core, the pressure reaches 100,000 bars. The gas changes state to a hot liquid. As the pressure reaches 1,000,000 bars, it changes into a new state again, into metallic hydrogen. Beneath this is a layer where ice is a soupy liquid mixture of water, methane, and ammonia under high temperature and pressures. Finally, in the very center is a rocky ice core. Saturn’s outer atmosphere consists of an estimated 93.2% of molecular hydrogen and about 6.7% of helium. The atmosphere is primarily composed of hydrogen with small amounts of helium and methane. Trace amounts of ammonia, acetyne, ethane, phosphine, and methane were found. The upper layer clouds on Saturn consist of ammonia crystals. The lower layer clouds appeared to be composed of water. Saturn rotates faster than any planet planet, except for Jupiter. Saturn has an average orbital speed of about 9.69 kilometers per second. Saturn takes 29 ½ earth years to finish one revolution around the sun. Saturn spins around once in only ten hours and thirty-nine minutes. Saturn’s orbital degree is 2.48 degrees. As Saturn travels around the sun, it spins on an axis, an imaginary line drawn through its center. Saturn is most likely known for its rings. Saturn has seven rings. Saturn’s rings are made up of ice particles that travel around the planet. Saturn’s rings consist mainly of billions of pieces of ice. Many of Saturn’s rings feature thin bands of varying brightness called ringlets. They are arranged in a line parallel to the zodiac. D, C, B, A, F, G, and E are the names of Saturn’s rings. They are listed in order from the closest to Saturn to the farthest. Saturn’s ring system makes the planet one of the most beautiful objects in the solar system. The A and B rings are bright; thought C ring is a bit fainter. The ring system has various gaps. The most known gap is the Cassini division, this division separates the A and B rings. The Enkee division splits the A ring. It is thought the main rings are really made up of large number of narrow ringlets. It is also thought that the rings may have been formed from larger moons that were shattered by impacts of comets and meteoroids. The rings composition is not known for certain, but they show a significant amount of water. The rings might be made up of ice bergs and or snowballs. Most of the elaborate structure of some of nearby satellites. These rings extend from 6,630 kilometers to 120,700 kilometers above Saturn’s equator. It is approximately 20 meters thick, and made up of 93 percent water and 7 percent amorphous carbon. Saturn’s rings have an intricate structure of thousands of thin gaps and ringlets. It is indicated that Saturn’s rings have their own atmosphere. The atmosphere is made up of molecular oxygen gas produced when ultra violet light from the sun interacts with water ice in the rings. The rings also have a similar hydroxide atmosphere like the oxygen gas; the atmosphere is produced by disintegration of water molecules Saturn shows complex patterns in its brightness. Most of the variability is due to the changing aspects of the rings, this goes through two cycles every orbit. Saturn has a lot of moons. The precise figure is indeterminate. As the orbiting of ice in Saturn’s rings are all technically moons .Sixty moons have been identified, and 3 more unconfirmed moons that could possibly be large dust clumped in the rings, Fifty- two of those moons have been given proper names. Most of those moons are very small in size. Thirty-four of those moons are less than 10 kilometers in diameter; another 13 of the moons are less than 50 kilometers. Only seven are large enough to have collapsed into hydrostatic equilibrium under their own gravitation. Titan is Saturn’s largest moons. It is the only moon to have a dense atmosphere. WHILE MOST OF Saturn’s moons are small, Titan on the other hand is huge! Titan is actually bigger than the planet Mercury. It is also the only moon to possess a significant atmosphere. Saturn’s second largest moon Rhea may have a tenuous ring system of its own. more
