The Ghost of a Dwarf Galaxy:
Fossils of the Hierarchical Formation of the Nearby Spiral Galaxy NGC 5907




This image of NGC 5907 was independently produced through a 24-inch, f/3 telescope located on the Greek Island of Crete by Stefan Binnewies and Josef Pöpsel, who operate the instrument remotely from their home in Germany. The 4 hour white light exposure was taken through a clear luminance filter and has been inverted to make the visibility of faint features more obvious. It displays the set of looping structures surrounding the main galaxy that were first reported by this international research team.
