Astronomers have succeeded in tracing a mysterious one-off burst of cosmic radio waves back to its host galaxy.
Mysterious radio burst detected in deep space traced back to its host galaxy; Identifying the sources of these radio bursts is a critical step toward solving the mystery of what triggers them
STUNNING: Fast Radio Bursts, brief yet brilliant eruptions of cosmic radio waves, have baffled astronomers since they were first reported nearly a decade ago.
Burning bright
It took a 25-year-old radio engineer and ham radio operator, Grote Reber, to conduct the first systematic survey of cosmic radio waves. In 1937 Reber single-handedly built a 9.5-meter (31.4-foot) radio telescope in his backyard in Wheaton, Illinois, and for nearly a decade was the world's only radio astronomer (S&T: July 1988, pages 28 and 31).

Yet with it they have taken a practical first step toward subtracting unwanted signals from astronomical measurements of cosmic radio waves.
A new weapon in the war against radio interference
Since Karl Jansky and Grote Reber first detected cosmic radio waves in the 1930s, the sensitivity and resolution of radio telescopes have improved dramatically.
