An informative survey of the cutting-edge science of X-ray astronomy. Two major space observatories launched recently -- NASA¿s ¿Chandra¿ and the European ¿Newton¿ -- are orbiting the Earth, sending back a gold mine of data on the X-ray universe. Schlegel describes the building and launching of this space-based X-ray observatory. He provides the background a non-scientist would need to grasp the present and follow the future of X-ray astronomy. He looks at the relatively brief history of the field, the hardware used to detect X rays, the satellites that have been or will be flown to collect these data, the way astronomers interpret these data, and, the insights we have already learned as well as speculations about what we may soon discover.
