cover: This frame from a numerical simulation shows the unhappy denouement for a neutron star that strays too close to a black hole. Most of the neutron star has been gobbled up by the central black hole; the remainder forms an orbiting disk, seen here in orange. The article on page 32 by Thomas Baumgarte and Stuart Shapiro contains other snapshots from the simulation and describes how numerical relativists deal with the challenge of black-hole physics and what they have learned from their simulations.
