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.

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?

TNO, in collaboration with KM3NeT, has detected the universe's most energetic neutrino at 220 PeV using a deep sea telescope.

What we have discovered is, we think, the most energetic neutrino ever recorded on Earth,” said Paul de Jong, a physicist at the University of Amsterdam and current spokesperson for the global collaboration of roughly 350 scientists who were involved in the discovery.

Physicists have detected the highest-energy 'ghost particle' ever felt on Earth, with nearly 100 times more energy than any neutrino previously detected.
