Neutrinos pervade the Universe as relics of the Big Bang, forming a nearly uniform cosmic neutrino background whose properties hold critical clues to the evolution of large-scale structure and ...

In the exotic world of particle physics, neutrinos may be the most mysterious members. They rarely interact with other matter, have almost no mass, and have no electrical charge. These characteristics ...

So much happened in the earliest moments of the universe. Elementary particles appeared, the first nuclei of hydrogen and helium, and fluctuations of energy and matter set into motion the formation of ...

Scientists with the IceCube Neutrino Observatory have unveiled a striking new image of our Milky Way galaxy as seen by ghost-like messenger particles called neutrinos. This new analysis—announced at a ...

Scientists have just detected a neutrino that is thirty times more energetic than any previously detected anywhere in the world. This exceptional discovery opens up new perspectives for understanding ...

Astrophysicists from the Universities of Oxford and Rome have for the first time found evidence of ripples in the Universe’s primordial sea of neutrinos, confirming the predictions of both Big Bang ...

The original version of this story appeared in Quanta Magazine. Of the 100 trillion neutrinos that pass through you every second, most come from the sun or Earth’s atmosphere. But a smattering of the ...

Ever since French physicist Pierre Auger proposed in 1939 that cosmic rays must carry incredible amounts of energy, scientists have puzzled over what could be producing these powerful clusters of ...

A distant galaxy nicknamed Shadow Blaster may have revealed a surprising source of cosmic neutrinos: extreme star formation instead of a supermassive black hole. The discovery suggests that hidden, ...

An extraordinary event consistent with a neutrino with an estimated energy of about 220 PeV (220 x 1015 electron volts or 220 million billion electron volts), was detected on February 13, 2023, by the ...
