A University of Colorado Denver engineer is on the cusp of giving scientists a new tool that can help them turn sci-fi into reality.

But if gamma-rays are just a form of light, ... If you were to race the highest-energy cosmic ray particle ever discovered with a photon to the Andromeda galaxy and back, ...

LST Collaboration Sheds Light on Brightest Gamma-Ray Burst Ever Detected. La Palma, Spain — The international LST Collaboration, in which the Department of Nuclear and Particle ...

Discovered by accident in the 1960s by U.S. military satellites developed to keep an eye on Soviet nuclear testing (which, too, produces gamma-rays), gamma-ray bursts remained a complete mystery ...

With the help of special telescopes, researchers have observed a cosmic particle accelerator as never before. Observations made with the gamma ray observatory H.E.S.S. in Namibia show for the ...

NASA's Fermi Gamma-ray Space Telescope has been mapping out the high-energy sky for several years. Here, Fermi scientists list 10 of their favorite gamma ray sources, from supernovas to black ...
