Mysterious World of Titan

    In our solar system the 6^th planet is Saturn, it is the 2^nd largest planet of our solar system. This is a gaseous planet. Because of the presence of the ring, this planet looks totally different from the other planets. Saturn has approximately 82 moon, Titan is one of them. Titan is the largest moon of Saturn and it is the second largest natural satellite of our solar system. Its diameter 5149.5 km and orbital period is 16 days. It was discovered on 25^th march 1655. It is fifty percent larger than earth's moon and its mass is 80% greater than moon. Apart from earth, titan has a dens atmosphere. Its surface is rocky and consists of ice crust. The surface of titan is covered with liquid methane. This is the main reason that the space scientists are curious about this planet. Scientists observed spontaneous liquid activity on this natural satellite. So, some of the scientists believe that some microorganisms can be present in the river of methane. Though there is no sign of life has been found on titan, scientists are hopeful to be found in near future. Even few scientists are hopeful that in near future Saturn can be our new home. It can be terraformed and a human colony can be established on this natural satellite of the planet Saturn. Titan’s atmosphere is Nitrogen rich and there may present water ice, these two factors could be the key of human colonization. In the year 2005 on 14^th January a probe of the European Space Agency (ESA) successfully landed on the titan. This probe confirmed the presence of water ice on titan. The photos from this probe confirmed the existence of large drainage channels throughout this natural satellite. After that all the space agencies of the world are getting interested about Titan. If there are present any extraterrestrial organisms on Titan, scientists are confident to find them. In the near future scientists are trying to reach Titan spontaneously and continue their research work.
