It was a flickering point of light, a blazar some nine billion light-years away. Every five years, it waxed and waned in brightness in a perfect sine wave, like clockwork. But that\u2019s not what made it special. What made it special is where the signal diverged from the pattern. Over nearly fifty years, this point of light had obeyed a clockwork cycle of five-year pulses \u2014 except for the twenty years where it didn\u2019t.<\/p>\n<p>Five other observatories confirmed the readings, including the University of Michigan Radio Astronomy Observatory, MIT\u2019s Haystack Observatory, the National Radio Astronomy Observatory (NRAO), Mets\u00e4hovi Radio Observatory in Finland, and NASA\u2019s Wide-field Infrared Survey Explorer (WISE) space satellite.
