Stellar monsters do not collide -- no hope for a spectacular catastrophe
Warsaw, Poland (SPX) Jul 17, 2013
One might expect that collisions between the remains of monstrous stars, with masses reaching 200-300 times that of our Sun, would be among the most spectacular phenomena in the Universe. Perhaps they are, but we will unfortunately probably never have the chance to find out. Astrophysicists from the Astronomical Observatory of the Faculty of Physics at University of Warsaw have discovered that the first such collisions will not occur until billions of years from now. For a long time, astronomers h ... read more
