The Hubble Space Telescope (HST) data of NGC 253 provide a detailed view of the central 5,800 light years. In the image to the left, the HST view is overlaid on a photograph (by David Malin) taken at the Anglo-Australian Observatory. This shows the relationship of the HST field of view to the full structure of this starbursting, barred spiral galaxy (diameter of 60,000 light years).
