Catching the Universe's Brightest, Fastest Radio Bursts with James Webb

This episode discusses the recent discovery of FRB 20250316A, one of the brightest fast radio bursts ever detected. Using the CHIME Outriggers array, researchers pinpointed its location in the galaxy NGC 4141. Subsequent observations with the James Webb Space Telescope revealed a faint infrared source near its origin, which could be a red giant or a massive star.

While these stars aren't the direct source, their presence suggests the burst might be caused by a nearby companion neutron star transferring mass or an isolated magnetar. This discovery provides vital clues for understanding the mysterious phenomenon of fast radio bursts.
