Resumen: Fast Radio Bursts (FRBs) are transient sources that emit a single radio flash with a duration of only a few milliseconds. They were firstly discovered only ten years ago, and nowadays we have detected a large number of these events using different radio facilities. However, their physical origin remains completely unknown. The derived cosmological distances make these events unexpectedly bright, and cannot be explained by known mechanisms. Multiple scenarios have been proposed during these years, but the true nature of FRBs still remains unclear. The detection of multiple bursts in a few FRBs excluded cataclysmic scenarios, however only a handful of FRBs have been precisely localized to date, associating them to host galaxies and, in a few cases, unveiling their local environments. These localizations reported surprising conditions that yet need to be related to the possible production of bursts. In this talk I am giving a review on FRBs, showing what we have learned about these events and what we have discovered in the last years. I will show the specific cases that have been precisely localized to milliarcsecond resolution and how this has contributed to the knowledge on the entire population of FRBs. Finally, I would discuss the possible paths that can be conducted in the coming years to reveal the nature of FRBs and to detect their putative burst emission at other wavelengths.
