That image is the same one I have been using for the background wallpaper for my slide decks in presentations lately, see the PPT deck at http://blogs.msdn.com/klevy/archive/2005/10/25/484955.aspx. But I don't think it is an actual photo, but instead a graphical artist rendering of what it might look like up close based on data they have on the object out there.
