Researchers at the University of Pennsylvania and NASA's Reactive Engine Laboratory have found that alien civilizations can discover radio signals that people exchange people with their spacecraft. The most likely moment of such a "wiretapping" is when the country and Mars coincide with the observer. The work was published in The Astrophysical Journal Letters (AJL).
"People mainly communicate other planets, such as Mars through the devices sent to study. However, the planet does not completely block the signal, and its leak can be found by the external observer, "explained the employment of the work at the University of Pennsylvania Pengchen Fan.
The scientists have analyzed the results of the twenty years of the global network of the global network of NASA's Antenna, which is connected with interplanetary missions. It turned out that most of the signals are especially aimed at Mars and Devices, which are located in Middle East.
According to the calculations, if the alien civilization observe the country and Mars, at 77% of cases, it will fall into the "beam" of one of our signals. In case of other planets, the probability is about 12%. Out of such configurations, the probability of failure is almost disappearing.
"We have shown that our own connection can tell us where the technologists, the signs of alien reconnaissance activities," said Jason Wright, a professor at the University of Pennsylvania.
According to estimates, Deep Space Network radio signals can be found up to 23 light years, using Mary comparable telescopes. The systems where the level of the orbits of the planets are next to the country are especially promising.
The authors emphasize that the volume of such programs will increase along with the development of research by solar system. This means that the probability of being observed in the universe is growing year by year.
