American astronomers who conducted on 305-meter radio telescope of Arecibo (Puerto Rico) is the most thorough in the history of the search for signals from extraterrestrial civilizations, finished an ambitious project.

Aliens have not been found, but hope remained.

The "Phoenix" has lasted 10 years. During this time, scientists attended 800 nearby stars by analyzing radio signals on the computer, trying to catch them "smart" component.

This was not the first experience of this kind, but the first time the "voice" of the cosmos listened with very high sensitivity and more than a billion of frequency channels.

Project Manager "Phoenix" Peter Bakas (Peter Backus) said that at the present sensitivity of instruments, the astronomers were able to detect radiation of extraterrestrial transmitters are equal in earthly power military radar, but located in the tens or hundreds of light-years away from us.

No project search for extraterrestrial artificial signals had so far this sensitivity.

A negative result does not mean that we are alone in the universe. It is possible that aliens use other methods of communication, and perhaps other civilizations located on the selected search area.


The new search will be undertaken in 2004. This time, astronomers use the latest Californian radio telescope Allen Telescope Array, consisting of 350 separate saucers by 6.1 meters in diameter.

These antennas are combined into complex, the total sensitivity of which will "listen" stars located a few times more than the candidates for "Phoenix."

The total number of stars, radio voices which will be analyzed in a new project, make a few hundred thousand.
