While the truth might be out there , technical aliens do n’t seem to be — at least not yet . Modern outcome from the most comprehensive Search for Extraterrestrial Intelligence ( SETI ) plan ever undertaken — which surveyed 1,327 nearby virtuoso for signals from intelligent beings — have turned up empty .
" There ’s certainly nothing out there glaringly obvious , " Danny Price , an astrophysicist at the University of California , Berkeley , and head author of a theme about the results , which were print inThe Astrophysical Journal , told Live Science . " There ’s no amazinglyadvanced civilizationstrying to meet us with incredibly potent transmitters . "
The radio telescope at Parkes Observatory in Australia revolves at night during routine maintenance.
While the team did n’t find anything this time around , Price said that there could be many explanations for the lack of exotic signals . Perhaps the search was conducted at the incorrect frequencies , or those signal were hide out by radio interference from Earth . Any such undertaking is limit by the methods and discoveries that humans happen to have made in the course of our own history .

" In a lot of way , SETI is a bit of a mirror back on ourselves and our own technology and our intellect of physics , " Price aver .
The search was conducted as part of theBreakthrough Listen opening move , a 10 - class , $ 100 - million enterprise fund by Israeli - Russian billionaire Yuri Milner that aim to glance over the skies fortechnosignatures : transmissions or other evidence created by technical creature on other human beings . The initiative , which sound off off in 2015 , relies on two of the world ’s most potent telescopes — the 328 - foot - diameter ( 100 meters ) Robert C. Byrd Green Bank Telescope in West Virginia , and the 210 - foot - diameter ( 64 yard ) Parkes Telescope in New South Wales , Australia — to endeavor to listen in on exotic communications .
In their in style information release , researchers analyzed 1 petabyte ( or 1 million gigabytes ) of data in both radio and optical wavelengths , looking at more than a thousand stars within 160 low-cal - years of Earth . Several thousandinteresting signalsappeared during the hunt , though all turned out to originate from mundane sources , like human - made satellites .
The entire gargantuan data catalog will be publicly useable on Breakthrough’sOpen Data Archive , making it the heavy publication of SETI data point in the story of the field .
Jason Wright , an astrophysicist at Pennsylvania State University who was not involve in the employment , told Live Science he was impressed with the researchers ' allegiance to public release of their data . " Anyone who thinks the team might have miss something can go over their results and see for themselves , " he said .
Wright has antecedently calculate that all SETI searches conducted to date amount to combing through the equivalent of a minuscule more thana hot tub ’s worth of waterin all of our satellite ’s oceans . The belated addition increase that by 50 % in radio wavelength , he said , or about another bathing tub ’s worth .
Price was affirmative that in the future his squad will be able-bodied to put more stringent demarcation line on the prevalence of life history in the universe . The researchers intend to expend the upcoming MeerKAT scope in South Africa , an observatory that will comprise of 64 separate 44 - animal foot - diameter ( 13.5 m ) arrays , to look more thana million adept in our galactic neighborhoodfor extraterrestrial contagion .
While any signal that appear would have to be carefully scrutinized to assure it was real , Price said such a finding would be truly revolutionary . " I think it would be one of the most authoritative discoveries human race would ever make , " he read .
