Fast radio bursts and cosmic events are frequently seen.

Astronomers have reported a fast radio burst (FRB). Whose characteristics are different from almost all other FRBs previously detected, except one. FRBs are bright flashes of light that appear for a few milliseconds and then vanish. Since the first FRB was discovered in 2007, 140 more were discovered until June 2021. Their origins are unknown, and their appearance is unpredictable. The new study in Nature describes FRB 20190520B, first discovered in 2019. What makes it different is that, unlike many other FRBs, it emits frequent, repeating bursts of radio waves. And between bursts, it constantly emits weaker radio waves. The detection and localization of the repeating FRB 190520B, which is co-located with a compact, persistent radio source and associated with a dwarf host galaxy of high specific star-formation.

Only one FRB has been previously observed to behave this way. Called FRB 121102, it was discovered in 2012.

Only one FRB has been previously observed to behave this way. Called FRB 121102, it was discovered in 2012. Calling the behavior strange, the US National Radio Astronomy Observatory (NRAO) said on its website. That discovery raises new questions about the nature of these mysterious objects and also about their usefulness as tools for studying the nature of intergalactic space. The scientists used the National Science Foundation’s Karl G Jansky Very Large Array (VLA) and other telescopes to study the object. The astronomers have suggested that there may be two different mechanisms producing FRBs. That the objects producing them may act differently at different stages. Among the candidates for the sources of FRBs are the superdense neutron stars left over after a supernova, or magnetars.
