Abstract Since the discovery of first fast radio burst (FRB) in 2007, and their confirmation as an abundant extragalactic population 2013, study these sources has expanded at incredible rate. In our 2019 review on subject, we presented a growing, but still mysterious, FRBs—60 unique sources, 2 repeating FRBs, only 1 identified host galaxy. However, few short years, new observations discoveries have given us wealth information about sources. The total FRB now stands over 600 published 24 repeaters, 19 galaxies. Higher time resolution data, sustained monitoring, precision localisations insight into galaxies, morphology, source activity, progenitor models, use FRBs cosmological probes. recent detection bright FRB-like from Galactic magnetar SGR 1935 + 2154 provides important link between magnetars. There also continue to be surprising discoveries, like periodic modulation activity repeaters localisation one relatively nearby globular cluster associated with M81 this review, summarise exciting observational results past years. We highlight impact understanding proposed models. build introduction earlier update readers results, discuss interesting avenues for exploration field enters regime where hundreds thousands will discovered reported each year.
