In the photograph of X-ray jets and point sources in the galaxy Centaurus A, shown in “Shocks jolt jet set galaxy, X rays reveal,” many of the point sources seem to be regularly spaced along arcs. The pattern is reminiscent of an X-ray diffraction pattern from a crystal (a microscopic event mirrored here on a […]
