New Twists Add More Mystery to the Fast Radio Burst Enigma

A composite image of the Milky Way above the Australia Telescope Compact Array, which has been utilised in the study of fast radio bursts in recent years. A series of recent discoveries, including the detection of the first-ever repeating fast radio burst, has added new layers to the existing mystery of this elusive […]
