The long-standing mystery of Gamma Ray bursts apparently has now been solved. Essentially, a relatively near occurrence was in a perfect position to be fully studied, and found to exhibit characteristics associated with a supernovae burst. Not only that, but it appears that Gamma Ray burst precede the actual observation of a supernovae itself - and thus we can predict supernovae through their direct corrolation to Gamma Ray bursts:
