In 1932, a Bell Labs engineer trying to solve mysterious static from transatlantic phone calls that repeated every 23 hours and 56 minutes accidentally discovered radio waves from the center of the Milky Way

In the early 1930s, Bell Labs engineer Karl Jansky embarked on an investigation into transatlantic radio interference. By constructing a large antenna to trace an enigmatic hiss, he uncovered a signal that deviated from known sources. This signal, which followed a sidereal day cycle, indicated a celestial origin. Jansky's serendipitous discovery not only identified radio emissions from the galaxy's center but also pioneered the exciting realm of radio astronomy.
