Description:
This image shows the galaxy group known as Stephan’s Quintet along with the spiral galaxy NGC7331 and a number of other galaxies (there are more then 20 in the image). NGC7331 is some 40 million light years away. The four galaxies to its upper right (known as The Fleas) are far in the background at a distance of over 300 million light years. Stephan’s Quintet was the first compact galaxy group discovered, by Edouard Stephan in 1877. While four of the galaxies are a real association lying at a distance of 210-340 million light years, NGC 7320 is a foreground object at a distance of around 40 million light years. Ironically as its distance matches that of NGC7331 it could be a member of that group rather than Stephan’s. The field of view is about 42 arc-minutes wide by 34 high.
