A huge detector in the Mediterranean Sea spotted the most energetic neutrino from space to date. The particle could shed light on the universe’s most extreme phenomena.

Astronomers using a giant network of sensors, still under construction at the bottom of the Mediterranean Sea, have found the highest-energy cosmic “ghost particle” ever detected.
