For a few hundred thousand years, our eyes were our primary astronomical tool, and we used them well. We catalogued and analyzed what we saw, filled in the gaps with powerful stories, applied what we knew of mathematics, and then invented complex tools of stone, metal, and glass to expand our knowledge. Everything we knew about the universe was based on light, that small part of the electromagnetic spectrum detectable by human eyes. Then one day in the 1930s, a young engineer named Karl Jansky was assigned a task at Bell Labs: What were the sources of radio static that could interrupt transatlantic radio communications? After several years of work, he identified one source as radio waves coming from thunderstorms near and far--and another, from something at the center of the Milky Way. For the very first time, we had detected radiation below the visible part of the spectrum emanating from an astronomical object. For years, astr
