These outbursts are similar to what is seen in a nuclear bomb explosion, and the first GRBs were detected by the Vela satellites that monitored nuclear testing. This graph shows the sudden increase in gamma rays recorded for the first GRB detected by the monitoring satellites in 1967. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/firstgrb_vela4/firstgrb_vela4.dc.xml Sun, 02 Jul 1967 12:00:00 GMT
