The IceCube neutrino detector has allowed researchers to resolve a debate about what types of particles make up ...
While slow-energy cosmic rays that strike Earth are known to originate from the sun, others with higher energies stream into the solar system from deep space.
For years, astronomers have searched for the origins of ultra-high-energy cosmic rays, the most powerful particles in the universe. These energetic travelers move at nearly the speed of light ...
Many of the gamma rays we see coming from the sun are produced by cosmic rays, which are charged particles that hurtle through space at incredible speeds.
Cosmic rays recorded in the atmosphere above California have dropped sharply thanks to the sun's increasing activity.
Most of the cosmic rays we get here on Earth come from the sun, but we’ve also picked up particles that we think are coming from other galaxies. Cosmic rays can tell us about space and the universe.
New research published by Michigan State University astrophysicists could help scientists answer a century-old question: Where did galactic cosmic rays come from?
New research details the discovery of the highest-energy light ever observed from the sun. The international team behind the discovery also found that this type of light, known as gamma rays, is ...
Scientists have detected a dramatic excess of gamma rays pouring out from the Sun, which represent the highest-energy light emissions ever detected from Earth’s star.
Scientists in Utah have identified a rare cosmic ray that could've come from beyond the Milky Way. It has been named the "Amaterasu particle" after the Japanese sun goddess. A Telescope Array ...
"Now we know where to look." While lower energy cosmic rays come from the Sun, other stars, and exploding stars, the origin of the highest energy rays has been a decades-long mystery.
