The majority of FRBs have been seen only once, although some are known to generate multiple flashes<SUP>2,3</SUP>. Many models invoke magnetically powered neutron stars (magnetars) as the source of the emission<SUP>4,5</SUP>. Recently, the discovery<SUP>6</SUP> of another repeater (FRB 20200120E) was announced, in the direction of the nearby galaxy M81, with four potential counterparts at other wavelengths<SUP>6</SUP>. Here we report observations that localized the FRB to a globular cluster associated with M81, where it is 2 parsecs away from the optical centre of the cluster. Globular clusters host old stellar populations, challenging FRB models that invoke young magnetars formed in a core-collapse supernova. We propose instead that FRB 20200120E originates from a highly magnetized neutron star formed either through the accretion-induced collapse of a white dwarf, or the merger of compact stars in a binary system<SUP>7</SUP>. Compact binaries are efficiently formed inside globular clusters, so a model invoking them could also be responsible for the observed bursts.STAMPAen10.1038/s41586-021-04354-whttps://www.nature.com/articles/s41586-021-04354-w2022Natur.602..585KFIS/05 - ASTRONOMIA E ASTROFISICA
