gamma-ray burst
In gamma-ray astronomy, gamma-ray bursts (GRBs) are extremely energetic events occurring in distant Galaxy, galaxies which represent the brightest and most powerful class of explosion in the universe. These extreme Electromagnetic radiation, ele ...
that was first observed on 29 July 2006. It is likely the signal of a
type Ic supernova—the core collapse of a massive star. It was also notable for its extraordinarily long X-ray
afterglow, detectable 642 days (nearly two years) after the original event. The event was remote, with a
redshift
In physics, a redshift is an increase in the wavelength, and corresponding decrease in the frequency and photon energy, of electromagnetic radiation (such as light). The opposite change, a decrease in wavelength and increase in frequency and e ...
