TL;DR: The authors' observations are inconsistent with the fast radio burst having a Galactic origin or its source being located within a prominent star-forming galaxy, and the source appears to be co-located with a low-luminosity active galactic nucleus or a previously unknown type of extragalactic source.

TL;DR: Only one repeating fast radio burst has been localized, to an irregular dwarf galaxy; now another is found to come from a star-forming region of a nearby spiral galaxy, suggesting that repeating FRBs may have a wide range of luminosities, and originate from diverse host galaxies and local environments.

TL;DR: In this article, the authors reported the precise localisation of a second repeating fast radio bursts (FRB 180916.J0158+65) to a star-forming region in a nearby (redshift $z = 0.0337 \pm 0.0002$) massive spiral galaxy, whose properties and proximity distinguish it from all known hosts.

TL;DR: In this paper, the authors reported the detection of a $16.35\pm 0.15$ day periodicity (or possibly a higher-frequency alias of that periodicity) from a repeating fast radio burst (FRB) 180916.J0158+65 detected by the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project (CHIME/FRB).

TL;DR: A periodicity of roughly 16 days is detected for the fast radio burst 180916.J0158+65, suggesting that the burst arises from a periodically modulated mechanism instead of a cataclysmic or sporadic process.
