A deep-sea detector glimpsed a particle with 220 million billion electron volts of energy — around 20 times as energetic as any neutrino seen before.

And trillions of them just flew through your body. What are they? Neutrinos ‒ and scientists Wednesday announced the discovery of the most powerful one ever seen. Neutrinos are ghostly subatomic ...

The neutrino, as the particle is formally known, is 30 times more energetic than any of the few hundreds of previously detected neutrinos. These tiny, high-energy particles from space are often ...

One called ARCA - 3,450 meters (2.1 miles) deep near Sicily - is designed to find high-energy neutrinos. One called ORCA - 2,450 meters (1.5 miles) deep near Provence, France - is designed to ...

Neutrinos detected by the IceCube telescope may originate from energetic supermassive black holes emitting radio waves, rather than the gamma ray-emitting galactic nuclei currently thought to be ...
