An international team of researchers has observed a gamma-ray burst with an afterglow featuring the highest-energy photons ever detected. These are a trillion times more energetic than visible light ever detected in a burst. "This very high energy emission had…
Gamma Ray Bursts (GRBs) are the brightest explosions in the Universe. They are detected by orbiting space telescopes at the rate of about one a day. The number that could be detected from Earth should be much higher than the current rate, but the efficiency of the…
A group of researchers observing a specific gamma ray burst (GRB) have found that its probable host galaxy is almost entirely deficient in molecular gas. Molecular gas has long been considered to be the main raw material used in the formation of stars. The current…
