Summary:
- Astronomers have detected a powerful radio burst from a giant dead galaxy located 3 billion light-years away from Earth.
- The radio burst is thought to have been produced by a magnetar, a type of neutron star with an extremely strong magnetic field, within the dead galaxy.
- This discovery provides insights into the nature of magnetars and the evolution of massive galaxies, as it suggests that even dead galaxies can still harbor active sources of radio emission.
