Lets know about the past!!
17 years ago, On 28-02-1997
GRB 970228 was the first gamma-ray burst (GRB) for which an afterglow was observed. Since 1993, physicists had predicted GRB's to be followed by a lower energy afterglow (such as radio waves, x-rays and even visible light) but until this event, GRB's had only been observed in highly luminous bursts of high-energy gamma rays (the most energetic form of EM Radiation).
The burst had multiple peaks in its light curve and lasted approximately 80 seconds. Peculiarities in the light curve of GRB 970228 suggested that a supernova may have occurred as well. The position of the burst coincided with a galaxy about 8.1 billion light-years away, providing that GRB's occur well beyond the galaxy.....!!!!!
