A pioneering researcher within the area of astronomy generally known as SETI, or the seek for extraterrestrial intelligence, Dan Werthimer’s work includes scanning the cosmos with large, ground-based radio telescopes to search for unusual or unexplained alerts that will have originated from alien civilizations.
In recent times, nonetheless, the seek for extraterrestrial intelligence has develop into much more difficult. Growing calls for for cellular providers and wi-fi web have crowded the radio spectrum, creating interference that may skew knowledge and add “noise” to scientific outcomes.
“Earth is simply getting increasingly more polluted,” mentioned Werthimer, chief technologist on the Berkeley SETI Analysis Middle. “With some radio bands, it is already unattainable to do SETI as a result of they’re so filled with tv transmitters, WiFI and cellphone bands.”
At its coronary heart, SETI analysis goals to reply the query: Are we alone within the universe? Within the many years since scientists first began listening for alien alerts, enhancements in telescope expertise and knowledge processing have bolstered the search, Werthimer mentioned.
Werthimer was not too long ago one of many authors of a pre-print research led by Chinese language researchers that recognized a radio sign that a number of information retailers mistakenly reported as having traits of an alien civilization. The sign was truly discovered to have been radio interference, Werthimer clarified.
