Astronomers have observed what might be the "perfect explosion," a colossal and utterly spherical blast triggered by the merger of two very dense stellar remnants called neutron stars shortly before the combined entity collapsed to form a black hole. "To be honest, we are really going back to the drawing board with this," Cosmic Dawn Center astrophysicist and study co-author …
What happens when two very dense stellar remnants collide? Astronomers have now observed one of these perfect explosions that was colossal and the blast was utterly spherical in nature, which happened as two neutron stars merged together. The two neutron stars collapsed to form a black hole as astronomers looked on. A perfectly spherical explosion, called a kilonova, that followed …
