A new study has revealed an unexpected link between solar storms and the flux of high-energy cosmic rays arriving at Earth.

In 1991, an experiment detected the highest-energy cosmic ray ever observed. Later dubbed the Oh-My-God particle, the cosmic ray’s energy shocked astrophysicists. Nothing in our galaxy had the power ...

More than one million sources of energy are featured in the first X-ray images from the eROSITA space telescope. By Laura Baisas Published Feb 5, 2024 12:00 PM EST Add Popular Science (opens in a new ...

A new theory suggests the universe is constantly recording its own history in the fabric of spacetime. If correct, this ...

A neutrino from space recently plunged into the Mediterranean Sea with an energy that blows all other known neutrinos out of the water. Packing a punch of some 220 million billion electron volts, this ...

Artist’s impression of an ultra-high energy cosmic ray reaching Earth. New research suggests that some of the highest-energy cosmic rays may consist of atomic nuclei heavier than iron. The background ...

Some of the most energetic cosmic rays in the galaxy may come from a surprisingly small source. If Max Planck Institute for Astrophysics researcher Laura Olivera-Nieto and her colleagues are right, ...

The expansion of the universe is still accelerating under the influence of dark energy, despite recent claims to the contrary ...
