Ancient Radio Signal Unearthed by Astronomers

Astronomers have discovered an eight billion-year-old radio signal, known as FRB 20220610A, which contained an extreme level of energy, equivalent to what the sun releases in 30 years. These fast radio bursts are difficult to study due to their short duration, but they are believed to result from galaxy mergers and could help measure the mass of elements in the universe. The signal was detected using the Australian SKA Pathfinder radio telescope and confirmed as the oldest and most remote example found so far.
