Neutrinos and antineutrinos are nearly massless particles produced in many nuclear reactions, including the fission of uranium in nuclear power plants on Earth and the fusion reactions at the core of ...

For the first time ever, scientists using NASA’s Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy. This neutrino traveled 3.7 billion years at ...

A group of Italian scientists have questioned those faster-than-light neutrino test results, claiming that anything moving that fast should lose energy — but that ...

How do astronomers look for neutrinos? These small, massless particles whiz through the universe at very close to the speed of light. They've been studied since the 1950s and detecting them provides ...

On September 22, 2021, the IceCube detector buried under Antarctic ice caught a neutrino carrying 750 trillion electron volts ...

Located 700 meters underground near the city of Jiangmen in southern China, a giant sphere—35 meters in diameter and filled with more than 20,000 tons of liquid—has just started a mission that will ...

A tiny particle that barely interacts with anything in the universe has helped scientists solve one of astronomy's long-standing mysteries. In 2021, the IceCube Neutrino Observatory buried deep in the ...
