The composite image combines an optical plus an X-ray EPIC view of NGC 1808, a barred spiral Seyfert 2 galaxy. The optical image was chosen to show the complex and extended spiral structure of the galaxy, while the X-ray emission reveals NGC 1808 as a starburst galaxy with intense star formation activity in the central region, as clearly seen in the lower left inset showing the X-ray emission only which is due to the presence of intense star formation activity and a hard unresolved source within the inner region.
