Scientist Discover another Mysterious, Repeating Radio Signal




Astronomers have found only the second example of a highly active, repeating fast radio burst with a compact source of weaker but persistent radio emission between bursts. The scientists used the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) and other telescopes to study the object, first discovered in 2019.
The object, called FRB 190520, was found by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China. A burst from the object occurred on May 20, 2019, and was found in data from that telescope in November of that year.
Follow-up observations with FAST showed that, unlike many other FRBs, it emits frequent, repeating bursts of radio waves.
