Et internationalt forskerhold har opfanget et udbrud af kosmiske radiobølger, som varer mindre end et millisekund. Dette hurtige radioudbrud (på engelsk "fast radio burst" - FRB) er det fjerneste, som endnu er set. Kilden til det blev isoleret med Det europæiske Sydobservatorium ESOs Very Large Telescope (VLT) i en galakse, som er så langt væk, at lyset og radiobølgerne fra den har brugt 8 milliarder på på at nå os. Dette FRB er tillige et af de mest energirige, som nogensinde er set; i en lille brøkdel af et sekund har det udsendt hvad der svarer til hele Solens energiudsendelse i løbet af 30 år.
