About this image

NGC 7331 is a spiral some 40 Mly away. The four galaxies to its upper right, though referred to as part of the 7331 Group, are actually far in the background at a distance of over 300 Mly. They are sometimes referred to as ‘The Fleas’.

Stephan's Quintet on the left is a compact galaxy group at a distance of 200-300 Mly. The brightest member of the group, NGC 7320, is not physically associated with the group, lying at a similar distance to NGC 7331.
