This animation shifts between two views of spiral galaxy NGC 4945. The first is a visible light image taken by XMM-Newton’s Optical Monitor, tinted blue. Overlain is a contour map of the iron K-alpha line observed by the telescope’s EPIC instrument. The second view shows a filled-in view of the contours where brighter colors indicate greater concentrations of X-rays.
