The results of a recent study by American astronomers, those searching for extraterrestrial intelligence will surely disappoint fans Fox Mulder’s ideas from the X-Files series. Researchers came to the conclusion that intelligent life is a very rare occurrence for our galaxy. A group of which one of the most famous alien hunters Jill Tarter (Jill Tarter) from the SETI Institute, was looking for reasonable signals for more than a hundred stars. It would seem that such a sample is completely not indicative of the Milky Way, which consists of two hundred billions of stars. During the search for extraterrestrial messages that started back in 1959, scientists examined many times more potential candidates. But this time the goals were not chosen by chance. According to the Kepler telescope, most of they have at least one planet within their habitable zones, which means that the probability of the existence of life there, in the form in which we know, is increasing significantly. Via Green Bank Telescope team during five minutes tested each system in the radio frequency range from 1.1 to 1.9 gigahertz. This gap corresponds to the signals which we ourselves send from Earth. Also two fall into it frequencies at which searches are conducted from the very beginning of the project. it frequency of 1,420 gigahertz, which corresponds to atomic radiation hydrogen, and 1,662 gigahertz characteristic of the hydroxyl group, part of the water. It is worth noting that with such a short-term the nature of observations in a narrow range can count on success only if the signal is purposefully sent to direction of the earth.

But anyway the study did not bring the desired results and the aliens not declared themselves. Details will be published in the article, accepted for publication in the Astrophysical Journal. However, the authors work is not discouraged. They are going to spend soon additional signal searches for individual systems at a time when their planets will line up in terms of Of the earth. This will allow to detect signals, if between such planets communication is ongoing. At the next stage of research, scientists plan look for signs of a connection between two exoplanets when they line up with the earth (illustration University of California, Berkeley). In the next step research scientists plan to look for signs of a connection between the two exoplanets when they line up in relation to Earth (illustration University of California, Berkeley). “We can just assume advanced intelligent civilizations intentionally or unintentionally use narrowband radio emission, the study says. – Thus, we looking for only certain types of civilizations, evaluate the general the number of varieties is too hard. “Key hopes extraterrestrial intelligence hunters are associated with heavy duty radio telescopes of the future. For example, the telescope Square Kilometre Array to be built by 2019 in Australia, New Zealand and South Africa will be able to pick up much weaker signals than all existing systems.
