Cosmic rays, consisting predominantly of high-energy protons and nuclei originating from distant astrophysical sources, interact continuously with the solar wind and the heliospheric magnetic fields.

The investigation of cosmic rays and their potential connection with dark matter occupies a central role in contemporary astrophysics. Recent experimental and theoretical advances have refined our ...

Our planet has recently been struck by an extraordinary burst of cosmic rays, demonstrating an intensity level that is unparalleled in recorded history. As we delve into the specifics of this event, ...

Scientists are seeking answers to a new outer space mystery after a telescope in Utah detected the most powerful cosmic ray seen in more than three decades, according to the authors of new research ...

Many massive stars explode as supernovae. If cosmic-ray baths are common in such environments, then the thermal histories that shaped Earth's interior may be common as well. This realization has ...

Scientists from the Telescope Array Collaboration have detected an ultrahigh-energy cosmic ray, a discovery that’s challenging our current understanding of exotic cosmic phenomena and their origins.

Milestone results released by the Large High Altitude Air Shower Observatory (LHAASO) on November 16 have solved a decades-old mystery about the cosmic ray energy spectrum—which shows a sharp decrease ...

Cosmic rays are particles from outer space that travel across the universe. They can be made by the sun, by other stars exploding, and even black holes. They move extremely fast, nearly the speed of ...

Michigan State University astrophysicists are closing in on one of space science’s biggest mysteries: where the galaxy’s most energetic particles come from. Their studies uncovered a pulsar wind ...

Earth is under constant bombardment by cosmic rays, showers of high-energy particles that blast our planet from all directions at near light speed. While this might sound like the precursor to a ...
