Ett internationellt forskarlag har upptäckt en avlägsen radiokälla som varade under kortare tid än en millisekund. Denna “radioblixt” (FRB, Fast Radio Burst) är den mest avlägsna som hittills har observerats. Källan lokaliserades med Europeiska sydobservatoriets Very Large Telescope (ESO:s VLT) i en galax så långt borta att ljuset tog åtta miljarder år att nå oss. Denna FRB är också en av de mest energirika som har studerats, då den under en bråkdels sekund frigjorde mer energi än vad solen utstrålar under trettio års tid.
