Description

This is a complete reprocessing of some old data. NGC 6722 is known as the Mimic Galaxy because it so closely resembles our understanding of our own galaxy the Milky Way: spiral arms wrapped around an elongated nucleus, with a satellite galaxy that might resemble the Magellanic Clouds.

NGC 7644 is one of the closest and largest spiral galaxies. It is almost twice the diameter of the Milky Way.
