A stunning new image of a cosmic jet has helped astronomers unlock the mystery behind the unusually bright emission of high-energy gamma rays and neutrinos from a peculiar celestial object. The source ...

Not every day does a particle from the outskirts of the universe crash through the Earth, lighting up thousands of detectors far beneath the ocean. But in the Mediterranean Sea, off the coast of ...

In space, energetic neutrinos are usually paired with energetic gamma rays. Galaxy NGC 1068, however, emits strong neutrinos and weak gamma rays, which presents a puzzle for scientists to solve. A new ...

In February of 2023, the Cubic Kilometer Neutrino Telescope (KM3NeT) detected a neutrino some 35 times higher in energy than any previous detection. A new study posits that this muon might be the ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.

"November 2017"--Title page verso. NASM copy purchased with funds from the S. Dillon Ripley Endowment. Introduction : Making mistakes -- Part I. The birth and youth of the neutrino. This crazy child - ...

No environment or object known in our galaxy could have produced a neutrino with so much energy. Earlier this year, an underwater detector in the Mediterranean Sea found the most energetic neutrino to ...

The last gasp of a primordial black hole may be the source of the highest-energy “ghost particle” detected to date, a new MIT study proposes. In a paper appearing today in Physical Review Letters, MIT ...

The most energetic cosmic neutrino, or "ghost particle," ever recorded may be the remnants of a nearby black hole explosion.
