Highest-energy light from a gamma-ray burst discovered
(World News Science)

An international team of researchers has observed a gamma-ray burst with an afterglow that featured the highest energy photons - a trillion times more energetic than visible light - ever detected in a burst. `This very high energy emission had been previously predicted in theoretical studies but never before directly observed,` said one of the researchers Alexander van der Horst, Assistant Professor of Physics at George Washington University in the US. Gamma-ray bursts are the most...
