The teams research describing the neutrino waspublishedtoday inNature.

TheCubic Kilometre Neutrino Telescope, or KM3NeT, made the newly described detection.

By the teams calculations, the muon had an energy of about 120 petaelectronvolts (PeV).

A single PeV is 1 quadrillion electron volts.

Thats impressive to us.

Neutrinos are vexingly tough to spot.

According to the IceCube Neutrino Observatory, about 100 trillion of the particles pass through your body every second.

If theres one of these sources directly in the then-much-smaller error box, thats interesting.
