Using an observatory under construction deep beneath the Mediterranean Sea near Sicily, scientists have detected a ghostly subatomic particle called a neutrino boasting record-breaking energy in another important step toward understanding some of the universe's most cataclysmic events.

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.

NEW YORK — A neutrino detector submerged in the Mediterranean Sea has sniffed out the most energetic ghost particle yet, scientists reported Wednesday. The newly detected neutrino is around 30 times more active than the previous recordholder. Scientists think it came from outside the Milky Way galaxy but its exact source remains a mystery.
