Was That a Dropped Call From Aliens? Unexplained Radio Beam from Star Has 'Excited' Scientists
News 18Nobody believes it was ET phoning, but radio astronomers admit they do not have an explanation yet for a beam of radio waves that apparently came from the direction of the star Proxima Centauri. “The signal appears to only show up in our data when we’re looking in the direction of Proxima Centauri, which is exciting,” Sheikh said. “We’ve seen these types of signal before, and it’s always turned out to be RFI — radio frequency interference,” Dan Werthimer, chief technologist at the Berkeley SETI Research Center, who is not part of the Proxima Centauri study, wrote in an email. Of the Proxima signal, Siemion said, “There have been some exclamations, but ‘wow’ hasn’t been one of them.” Asked what they were, he laughed. Normally, a radio telescope would point at a star or other target for five minutes and then “nod” slightly away from it for five minutes to see if the signal persisted.
