Gamma rays can only be detected by sensors made of dense metals and takes over six feet (1.8 meters) of concrete to block. When you purchase through links on our site, we may earn an affiliate ...

Gamma rays (denoted as γ) are electromagnetic radiation of high energy. They are produced by sub-atomic particle interactions, such as electron-positron annihilation, neutral pion decay, radioactive ...

Gamma-rays are the highest energy (the shortest wavelength) type of electromagnetic radiation. They are classified as a type of an ionising radiation; with respect to alpha and beta particles they ...

Yesterday, NASA released the first set of images from its newest space telescope, the Gamma-Ray Large Area Space Telescope, which has now been renamed Fermi in honor of the particle physicist Enrico ...

Astronomers have succeeded in quantifying the proton and electron components of cosmic rays in a supernova remnant. At least 70% of the very-high-energy gamma rays emitted from cosmic rays are due to ...

It’s always nice when something exceeds your expectations. When the thing in question is a spinning neutron star and your expectations are how much energy it releases, though, it’s very puzzling. The ...

A glowing blob known as “the cocoon”, which appears to be inside one of the enormous gamma-ray emanations from the centre of our galaxy dubbed the “Fermi bubbles”, has puzzled astronomers since it was ...

Roland Crocker receives funding from the Australian Research Council. A glowing blob known as “the cocoon”, which appears to be inside one of the enormous gamma-ray emanations from the centre of our ...
