Mysterious radio signals have long been a mainstay of science fiction tales, but lately they’ve also been the subject of serious scientific scrutiny. Radio bursts originating from deep spacehave become a hot topic in the astronomy world, and while most of these appear to be naturally occurring, you never know when one of them turns out to be something far stranger. At least, we can hope one of them will. Here on boring planet Earth, mysterious radio signals often pop up in the form of pirated transmissions broadcasting strange, cryptic messages. While most of these turn out to be merely hoaxes or pranks, many of them also remain unexplained.
Just this week, physicists studying cosmic rays in Antarctica have uncovered a strange radio signal that appears to have a mysterious origin. The physicists are part of the Antarctic Impulsive Transient Antenna (ANITA) program, a project which uses balloons to locate and identify signals produced by strange particles travelling from deep space as they collide with the Earth. However, this latest signal appears to originate from deep within the Earth itself. Is this a lost race of molemen and molewomen’s attempt at communication with us surface dwellers?
