The brief
Scientists have successfully recorded a neutrino "whisper" originating from all supernovae in the universe for the first time. This phenomenon is linked to core-collapse supernovae, where 99% of the energy released is invisible.
Coverage from Big Think, Universe Today, Universe Space Tech, and MSN emphasizes the detection of these ghost particles and the scale of the observation, which involves a billion supernovae at once. Future attention will focus on the analysis of these faint signals to better understand the invisible energy released during stellar collapses.
