Researchers believe they have traced the origin of the most energetic neutrino ever recorded.
The particle slammed into detection equipment positioned in the Mediterranean Sea.
Neutrinos are subatomic particles that rarely interact with matter, making high-energy detections especially notable.
Scientists used observatory data to work backward from the collision event toward a likely source in deep space.
The identification effort involved correlating the neutrino signal with other astronomical observations where possible.
Detectors submerged or placed near the Mediterranean are part of a global network designed to capture such rare events.
Pinpointing a source for an ultra-high-energy neutrino can help astronomers study extreme environments such as active galactic cores.
The finding marks a step forward in multi-messenger astronomy, which combines signals from different types of cosmic messengers.
Researchers said the neutrino’s energy level set it apart from the vast majority of previously detected particles.
Additional observations may be needed to fully confirm the proposed origin of the event.
