NEW YORK (AP) — 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.

Physicists have detected the highest-energy neutrino ever felt on Earth. The neutrino, detected at the bottom of the Mediterranean Sea, has nearly 100 times more energy than any ghost particle previously detected.

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 “ghost particle” discovered by a detector in the Mediterranean carried 30 times more energy than any neutrino observed to date
