COVER Artist's impression of the hottest tango in the Universe: A torus formed from the debris of a star spins around a rotating black hole. The black hole feeds energy to the torus, which in turn radiates it away as unseen gravitational waves. At the same time, jets of energy are released along the black hole's axis of rotation as input to cosmological gamma-ray bursts. 1874 [Image: P. F. A. M. van Putten]
