Watching a cannibal galaxy dine

This image of the central parts of Centaurus A reveals the parallelogram-shaped remains of a smaller galaxy that was gulped down about 200 to 700 million years ago. The image is based on data collected with the SOFI instrument on ESO's New Technology Telescope at La Silla. The original image, obtained by observing in the near-infrared through three different filters (J, H and K) was specially processed to look through the dust, providing a clear view of the center. The field of view is about 4 x 4 arcminutes.Centaurus A (NGC 5128) is the nearest giant, elliptical galaxy, at a distance of about 11 million light-years. One of the most studied objects in the southern sky, by 1847...
