In March 2023, astronomers observed GRB 230307A, the second-brightest known γ-ray burst. The focus shifted to the faint, colorful glow following the burst, transitioning from blue to deep red over weeks. Levan et al. and Yang et al. suggest that this red hue resulted from rare isotopes created during the triggering event, shedding light on cosmic element origins and raising questions about GRB causes.
