Astrophysicists try to infer the temperature and density of the accretion disk and the forces that shape it from the x-ray spectrum, but until recently they had nothing on Earth against which to check their results. Now they do, thanks to an earth-shaking experiment at Sandia National Laboratories in Albuquerque, New Mexico, called the Z-pinch--the world's most powerful x-ray source.
