The sun is located about 26,000 light-years from the center of our galaxy, aka the Milky Way, and its orbit is close to ...
Cosmic radiation could be a boon for subsurface life on worlds such as Europa (left), Mars (center) and Enceladus (right), according to a new study. The traditional astrophysical recipe for life as we ...
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.
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 sprawling Auger Cosmic Ray Observatory in South America has produced its first major discovery while still under construction. The international Auger collaboration has traced the rain of ...
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 ...
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 ...
The Large High Altitude Air Shower Observatory (LHAASO) has discovered a giant ultra-high-energy gamma-ray bubble structure in the Cygnus star-forming region, which is the first time that the origin ...
