Scientists have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 tera-electronvolts, or about ten trillion times the energy ...

A lead halide material can detect and image single gamma-ray photons with both high-spatial and high-energy resolution ...

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 ...

The crack of lightning has always seemed straightforward — clouds build up electric charge, and eventually, it snaps. But the chain of events that lights the sky has remained an atmospheric puzzle for ...

"Fermi is the most sensitive gamma-ray telescope in orbit, so when it doesn’t detect an expected signal, scientists must explain the absence." When you purchase through links on our site, we may earn ...

On the morning of October 9, astronomers’ inboxes pinged with a relatively modest alert: NASA’s Swift Observatory had just detected a fresh burst of energy, assumed to be coming from somewhere within ...
