Jamie Carter is an award-winning reporter who covers the night sky. A massive burst of gamma rays produced by the explosion of a star almost two billion light-years away was so powerful that it ...

Scientists from the CNRS, a consortium of German universities, and the Max-Planck-Institut für Kernphysik working at the ...

A team of researchers has successfully demonstrated nonlinear Compton scattering (NCS) between an ultra-relativistic electron ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film ...

It's not easy to imagine how high the frequency of a high-energy gamma ray is. During the time it takes for its wave to go through one cycle, a gamma-ray wave traveling at the speed of light will ...

This site presents the energy and photon intensity of gamma rays as seen in thermal-neutron capture in two tables, one in ascending order of gamma energy and a second organized by Z, A of the target.

Satellites captured images of how the gamma blast lit up dust rings in space Scientists have revealed how Nasa satellites detected the brightest gamma ray explosion in space. The gamma-ray burst ...
