Summary

Story summary

An international team, including University of Toronto researchers, identified the brightest Fast Radio Burst, RBFLOAT, from galaxy NGC 4141 about 130 million light-years away.
It was detected on March 16, 2025.
CHIME/FRB Outrigger pinpointed the location, enabling JWST follow-up.
JWST follow-up found a faint infrared signal possibly linked to a red giant or light echo.
The non-repeating nature of RBFLOAT challenges existing FRB theories, suggesting diverse origins.
