APOD 4.1

Stephan's Quintet Plus One
This image of Stephan's Quintet was formulated with data from the Hubble Legacy Archive and the Subaru Telescope. Only 4 of the 5 galaxies are locked in a "cosmic dance", the closest galaxies being 300 million light years away. They all have distorted loops and tails spawning out of their shape due to gravitational tides. Stephan's quintet is within the boundaries of the Pegasus constellation. NGC 7320C is the galaxy that is all the way to the left that is the outlier. This is an incredible image because it shows a distance of 500 million light years and understates how large these galaxies truly are.
