Astronomers reveal fast FRBs have been discovered coming from the same mystery cosmic source

FRBs are mystery radio bursts from deep space that last for just a few milliseconds.

Six additional repeating fast radio bursts have been discovered coming the same unknown source in space. The FRBs came from the same region beyond the Milky Way where 10 bursts had previously been detected – and their discovery should give a greater insight into what caused them.

FRBs are radio signals from deep space that last just a few milliseconds. The first FRB was detected in 2001 and since then over a dozen have been found in telescope data. However, these all appeared to be one-off events, with no two bursts coming from the same location. This means follow-up observations were not possible, keeping their source a mystery.

Current theories as to their cause involve a cataclysmic event like a neutron star collapsing into a black hole or a supernova. Another option is they are coming from a young, highly magnetised, extragalactic neutron star.

In March, scientists announced the discovery of the first repeating FRBs. Ten bursts were recorded coming from the same direction as FRB 121102 – a spot in space far beyond the Milky Way.

Their findings, published in the journal Nature, showed the bursts had the same dispersion measurements as the original FRB, indicating the source must have survived whatever event produced the FRB in the first place. As a result, the bursts cannot be being produced by a one-off event. Read more >>>
