Cosmic Ray Mystery Solved
November 2, 2009—Star explosions can act like ultra-powerful particle colliders in space, creating what are known as cosmic rays, new research shows. Cosmic rays, which are actually high-energy subatomic particles, are...
Galaxy's Dying Stars Confirm Cosmic Ray Source (SPACE.com)
Recent photographs of an active galaxy offer new confirmation for the idea that supernova explosions are the creators of surprisingly energetic particles called cosmic rays. Cosmic rays are protons that whiz through space at...
Cosmic-Ray Mystery Traced to Star-Birth Frenzy
WASHINGTON, D.C. — Astronomers have for the first time traced gamma rays, the most energetic form of light, to galaxies undergoing a frenzy of star birth. The finding, which has revealed a new class of galactic gamma-ray...

VERITAS telescopes help solve 100-year-old mystery: The origin of cosmic rays
Nearly 100 years ago, scientists detected the first signs of cosmic rays - subatomic particles (mostly protons) that zip through space at nearly the speed of light. New evidence from the VERITAS telescope array shows that...
Iowa State researchers contribute to discovery of gamma rays from starburst galaxy
AMES, Iowa - Iowa State University astrophysicists contributed to the recent discovery that a galaxy quickly creating new stars is also a source of high energy gamma rays. The study reports that researchers using the VERITAS...
NASA's Fermi Telescope Detects Gamma-Ray From
Nearby galaxies undergoing a furious pace of star formation also emit lots of gamma rays, say astronomers using NASA's Fermi Gamma-ray Space Telescope. Two so-called "starburst" galaxies, plus a satellite of our own Milky Way...
