radio waves: Astronomers unlock the secrets of 8 billion year old radio bursts
Astronomers have made a groundbreaking discovery after detecting a fast radio burst (FRB) that occurred 8 billion years ago. This particular FRB, known as FRB 20220610A, released an amount of energy equivalent to the suns emissions over three decades in less than a millisecond. The FRB was detected using the ASKAP array of radio telescopes in Australia and its source was found to be an older galaxy that is further away than any other known FRB source.
