Scientists detect more bizarre radio bursts from deep space, still can’t explain where they come from


FRBs last only fractions of a second before disappearing. They are unpredictable and follow no obvious pattern. This most recent FRB sighting comes from Australia’s Parkes Observatory where three distinct radio bursts were detected in rapid succession. The first burst, detected on March 1st, was followed by subsequent radio bursts on March 9th and 11th.

It was the March 9th signal that is most interesting to astronomers, due to its size. It boasted a signal-to-noise ratio of 411, making it the strongest FRB ever recorded by a large margin. As New Atlas explains, the second brightest burst had a signal-to-noise ratio of around 90, with most FRBs falling between 10 and 40 on the same scale.

The mystery of where fast radio bursts come from has fascinated scientists for a long time, but a few theories are currently leading the pack. Some researchers believe that supernovas are responsible for the bright signal bursts, with the radio waves of a distant star’s supernova arriving long after the light of the event would have been visible to us. By the time we hear the signal, the actual supernova event has long since fizzled out, making it appear as though the bursts are originating from nothing at all. Or, maybe it’s aliens? Yeah, it’s probably aliens. – READ MORE
