Scientists have been searching for aliens for centuries، but new research reveals that if intelligent extraterrestrial life exists، it's likely not anywhere nearby، as the Technical Times said.
As part of the decade-long $100 million Breakthrough Listen initiative funded by Russian billionaire Yuri Milner، researchers conducted the most comprehensive Search for Extraterrestrial Intelligence program ever undertaken. The team led by University of California، Berkeley astrophysicist Danny Price looked at 1،327 nearby stars across billions of frequency channels in an attempt to detect signs of intelligent life.
Results of their search was released in a paper published in the Astrophysical Journal with the researchers revealing that they came up empty.
Ambitious Project Finds Nothing Nearby Breakthrough Listen used the Green Bank Radio Telescope in West Virginia and CSIRO's Parkes Radio Telescope in Australia to scan the cosmos for "technosignatures،" which are transmissions or other evidence of technologically savvy life forms from other worlds. The 1،327 stars were all observed at the radio frequencies ranging from 1 to 10 gigahertz.
For the recent release، the researchers scoured 1 petabyte of data using various techniques، including looking for signals within a narrow range of radio frequencies and scanning for bright lasers that may be indicative of alien communication or propulsion.
With events consistent with terrestrial activities excluded، the team found themselves with zero candidates of extraterrestrial activity over the last three years. It turns out، there aren't aliens out there reaching out to Earth through advanced technology.
