No Alien Signals Detected in Kepler SETI Search

In an effort to search for intelligent extraterrestrials, SETI astronomers have completed their first “directed” search. Unfortunately, it turned up no evidence of transmitting aliens. But that’s hardly surprising.

By focusing the Green Bank radio telescope, located in West Virginia, on stars hosting (candidate) exoplanets, it is hoped that one of those star systems may also play host to a sufficiently evolved alien race capable of transmitting radio signals into space. But in a study headed by ex-SETI chief Jill Tarter, the conclusion of this first attempt is blunt: “No signals of extraterrestrial origin were found.”

With the help of the Kepler space telescope, Tarter and her team were able to identify which stars in Kepler’s field of view host exoplanets with certain characteristics. By selecting star systems hosting worlds in their habitable zones, systems containing 5 or more exoplanets and super-Earths with an orbital period of over 50 days, the astronomers hope that the evolution of intelligent life may have been possible, and thus may contain a transmitting alien race.

But it’s a bit like trying to find a needle in a haystack, when you have no clue where the haystack is.
