Study finds source of 'ghost emissions' that faded in 25yrs
Researches have found a bright source of radio emissions that came into existence in the 1990s. The source, which faded over for the next 25 years, is believed to be the afterglow of the explosion of a massive star, a researcher claimed. It emitted a long-duration gamma-ray burst which is an extremely energetic explosion observed in distant galaxies.
