Scientists have proposed a new way to search for aliens

James Guilohon and Abraham Loeb of the Harvard-Smithsonian Center for Astrophysics предложили conduct searches activity of other civilizations in the microwave range. They argue offer the ability to create interplanetary aircrafts out under similar solar sail - only instead of the sun on the sails can affect directional beam of microwave radiation. Leaks of the radiation escaped into space, and offer scientists track.

Restrictions on chemical fuel rockets, do not allow them on the basis of how a fast spaceship. Mission unmanned aircraft, flown away from us to the edges of the solar system, based on a ballistic trajectory.

Alternative engine technology is raise more questions than answers . Perhaps the solar sail - one of the most promising technologies that actively began testing this year . But this sail can work not only on the solar wind. If we are to the Earth (or Moon) sent the ship a powerful beam of microwave radiation, we can effectively accelerate and push it up a good speed.

Guilohon and Loeb reasoned , that if the technology is within the reach of the earthlings - means other intelligent life forms could well use it. But the use of such engines are inevitable leakage of microwave radiation (from the edges of sails, or as a result of errors, for example). These leaks, as the authors of the work, it will be able to fix a network of radio telescopes involved in the project are now SETI.

Radiation is likely to occur in short pulses that are repeated with a certain periodicity. A search for such pulses can not random, but based on extensive data of the existence of habitable exoplanets, found that during his work Kepler telescope.

By the way, the project SETI will soon receive substantial financial support from the our compatriot, Yuri Milner (co-owner Mail.ru Group , DST Global). The new initiative Breakthrough Initiatives , the announcement of which was made in July 2015, involves a ten-year investment of $ 100 million.

The initiative will consist of two parts. First, Breakthrough Listen, with SETI, listens more than a million stars in the search for extraterrestrial life. Second, Breakthrough Message, will be engaged in the preparation and sending greeting messages aliens, representing humanity and our planet.

Project SETI ( Search for Extraterrestrial Intelligence ) - a set of measures to search for extraterrestrial life and the possible entry into contact with them. Many modern scholars believe that in our galaxy there are many liveable planets that could appear intelligent life. Consequently, there is a chance to catch the radio waves emitted by some civilization. Participating in the project of radio telescopes collect data on scanning, which are then processed in the search for signals of artificial origin.
