SETI project with the Kepler telescope discovered the first in the history of the signal, a candidate for extraterrestrial radio signals.
In order to detect radio waves and signals, devices that emit a hypothetical extraterrestrial intelligence, it would be nice to know exactly where to look for these signals. After all, space, after all, a very big place, and the probability of chance upon an alien television signal is very, very low. Now, using data obtained by NASA's space telescope Kepler, astronomers have focused on the search for radio star systems, where there are planets that could support the emergence and existence of life on the surface. And it almost immediately produced results, recently discovered a radio signal, which is the most suitable candidate for a signal from an extraterrestrial civilization.
Of course, it is too early to shout "we found aliens," and uncork the champagne. There is a very high probability that the signal is caught terrestrial origin and is a reflection of our own signals from any celestial body.
"We have only recently started to use the program in conjunction with the SETI telescope Kepler and immediately found several candidates for signals of extraterrestrial origin" — said in a press release, a team of scientists, astronomers from the University of California at Berkeley. — "Unfortunately, the majority of the first candidate signals are not alien radio transmissions, they are traces of terrestrial radio frequency signals and noise."
"However, among many of the detected signals, there are some who, we believe, can be produced by extraterrestrial technology. These signals are very narrow in frequency, much narrower than the signals generated by any known astrophysical phenomena. These signals are constantly drifting in frequency, which can be explained by the Doppler effect, which occurs because of the superposition of movement of the transmitter and receiver, the actual telescope. "
Of course, the fact that SETI radio telescopes to send their star systems where exoplanets similar to Earth, greatly increases the chance of finding alien civilizations that have passed the phase of technological development, transferable powerful radio signals.
But considering the infinity of space and a huge number of star systems that Kepler telescope opens a "pack a day", the probability of detecting alien is still very low.
