SYDNEY, Australia, Oct. 12, 2026 - The James Webb Space Telescope has traced FRB 20240304B, the most distant fast radio burst ever detected, back to a host galaxy existing roughly 3 billion years after the Big Bang.^[1] South Africa's MeerKAT radio telescope first detected this burst on March 4, 2024.^[2] A team led by Manisha Caleb and Themiya Nanayakkara of the University of Sydney turned to the James Webb Space Telescope after ground-based telescopes failed to find the origin of the signal.^[3] Researchers using the telescope confirmed the burst resides in a small distant galaxy.^[4] Observational data from the Hubble, TESS and FUSE space telescopes was also used for this discovery work.^[5] Impact Insight. Fast radio bursts are flashes of radio waves lasting a few thousandths of a second that come from far beyond our galaxy, and what produces them is still debated. There is no direct planetary-defense link: this is distant astrophysics, included for readers who follow what space telescopes are finding.
