“Astronomers have detected the first-ever ‘radio signal’ coming from the interstellar comet 3I/ATLAS, right as it passed the halfway mark on its oneway trip through the solar system. And while this may seem like ostensible proof of the comet’s supposed alien origins — it’s actually the complete opposite. … the signals did not have a technological origin. Instead, they are the result of specific wavelength absorption related to the presence of hydroxyl radicals, or OH molecules, in the comet’s coma. These radicals are formed by the breakdown of water molecules as they are ejected from the comet via a natural process known as outgassing, which is a clear sign of cometary activity, according to a 2016 study.” (11/11/25)
