Story summary

Astronomers have made a groundbreaking discovery, tracing the fast radio burst FRB 20190208A to a distant dwarf galaxy over 7 billion light-years away. This revelation upends previous beliefs that only massive galaxies host these bursts, hinting that dwarf galaxies might create the perfect environment for repeating FRBs linked to explosive star events. The findings are detailed in The Astrophysical Journal Letters.
