Chandra Snaps Superbubbles in Galaxy Cluster

Scientists using the Chandra X-ray Observatory have documented the existence and longevity of buoyant magnetic bubbles in a distant galaxy cluster. And in doing so, they may have discovered how magnetic fields came to permeate galaxy clusters — the largest gravitationally bound structures in the universe. Brian McNamara (Ohio University, Athens) and his colleagues...
