NASA Webb Finds the Most Distant Fast Radio Burst Ever
A mysterious flash of radio energy from the distant universe has given astronomers a remarkable opportunity to investigate the early history of the cosmos. Using NASA's James Webb Space Telescope, researchers have identified the host galaxy of the most distant known fast radio burst, a brief but powerful signal that lasted only milliseconds. The event, known as FRB 20240304B , originated when the universe was approximately 3 billion years old. Even more surprising, the signal came from a small dwarf galaxy actively forming stars rather than the larger galaxy astronomers might have expected. The discovery, announced by NASA on October 8, 2026, could help scientists understand what produces fast radio bursts, how galaxies evolved in the early universe, and what lies between distant galaxies and Earth.
