The Hubble Space Telescope takes images of a very small part of the sky, and the galaxy was too large to fit, so this picture is a mosaic of six Hubble images. The full image, which is not available here, is 91 megapixels! You can get it here
. Many of the images on this page are pieces of the full sized image.
