In a recent discovery, experts have found a distant stellar explosion that did not behave in the manner expected from such a cosmic event. Namely, the supernova had some of the traits similar to a powerful gamma-ray burst (GRB), but was not exactly either of the two phenomena. Astrophysicists believe that future stud... |
