Scientists have detected the highest-energy ghost particle neutrino ever, but did it come from a supermassive black hole particle accelerator aiming its jet straight at Earth, or from a cosmic fossil?

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.

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.

Two years ago, a neutrino collided with matter and produced a tiny particle called a muon that pinged through the underwater detector, producing flashes of blue light. The researc

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