Key Questions Answered
FRB 20240304B is a mysterious Fast Radio Burst emitted from a galaxy located approximately 10 billion light-years away. This signal dates back to a time when the universe was only about 3 billion years old, shattering previous distance records for such bursts.
After the MeerKAT radio telescope network detected the burst and determined its coordinates, initial ground-based observations revealed no visible galaxy due to its faintness. The research team then used the James Webb Space Telescope's Near-Infrared Camera to capture deep images, revealing an extremely faint host galaxy.
Researchers believe that this Fast Radio Burst may be related to a magnetar, which is a type of neutron star with an extremely powerful magnetic field formed after a massive star's explosion. However, the discovery does not definitively confirm whether all FRBs share the same origin.
