People have long wondered – are we alone in the universe? According to scientists working at a research institute Extraterrestrial Intelligence (SETI), this question can be answered in very near future. Seth Shostak, Senior Astronomer, SETI Institute, stated: “Although at the moment the existence of life outside Earth is not proved, at any moment everything can radically change. “He also added that to seek life outside On our planet, scientists use three different effective methods. The first method is to search for microscopic alien creatures or their the remains. Research includes automated missions to Mars, where, according to scientists, there may be clear signs potentially habitable living environment. Also in solar Mars is not the only object of research. Shostak believes that there are at least half a dozen other worlds that can be quite livable. For example, ice satellites Jupiter, Europe and Ganymede, hid underground in their bowels oceans in whose waters life is likely to be found. Or, for example, Saturn’s satellite Titan contains lakes of liquid methane, which can also be very attractive to some life forms. The Second Method of Finding Life Beyond the Earth involves studying the atmospheres of planets in orbits around others stars to detect traces of oxygen, methane and other gases, which can only be produced using biological processes. In order to discover such planets, their atmosphere should be tight enough. The third alien search plan Life includes the innovative SETI project. The essence of this project – an active search in the bowels of the universe for any radio, optical and infrared signals coming from extraterrestrial civilizations. Determining the success of a revolutionary program is quite difficult. Shostak says that the opportunity to evaluate the effectiveness of the project will appear only when, using this method, specialists can Explore several million star systems. “Given modern advances in technology, it will be possible to implement in the next 20 years, “said Shostak. Based on data from the NASA telescope, in orbit around each of the 4 billion stars in our galaxy in about 1.6 planets are located on average, and every fifth planet is a potential “sister” of our earth. It means that the Milky Way alone contains tens of billions potentially inhabited planets. “If our Earth would be the only planet on which rational exists and develops life – it would be very unusual, “said Shostak.” I express the hope that intelligent life not only exists elsewhere Universe, but also in the near future will be discovered. It will give humanity is not only the knowledge and experience accumulated by other worlds, but also the realization that we are not alone, “added the scientist.
