Massive eruption on dead star pushes particles to cosmic speed limit
A burned-out stellar core produced a shockwave that pushed particles to their theoretical speed limit, scientists have reported. Astronomers used a gamma-ray observatory in Namibia called the High Energy Stereoscopic System (HESS) to show how an eruption creates a shock wave that accelerates material around it super-fast speeds. The research focused on RS Ophiuchi, a … Read more
