Revolutionary Observatory Predicts Core-Collapse Supernovae Pre-Explosion

The Jiangmen Underground Neutrino Observatory (JUNO) aims to detect neutrino events in near real-time, providing an early warning system for core-collapse supernovae. By localizing the neutrino source quickly, other observatories can focus on the region of the sky to observe the supernova as it occurs. JUNO's design allows for the detection of neutrinos from a core collapse up to a million light-years away and even the fainter burst of neutrinos in the pre-supernova stage up to 3,000 light-years away. JUNO is expected to be operational by the end of this year.
