The highly energetic explosion was initially attributed to a burst of gamma rays emitted either by the collision of two neutron stars or from the death of a massive star. Soon, however ...

A massive burst of gamma rays produced by the explosion of a star ... Earth’s ionosphere was disturbed for several hours by the blast. Enough energy arrived at Earth to activate lightning ...

After arriving at the station, BurstCube will be unpacked and later released into orbit, where it will detect, locate, and study short gamma-ray bursts—brief flashes of high-energy light.

These events are known as fast X-ray transients (FXRT), and the newly spotted blast has been designated ... the energy output was consistent with a gamma-ray burst dating back to when the universe ...
