A stunning image of NGC 660, a polar ring galaxy in the constellation Pisces, over 20 million light-years away. Its unique ring structure, almost perpendicular to its galactic disk, is believed to be the result of captured material from a passing galaxy. The image shows the galaxy amidst a scattered field of stars. The ring spans approximately 40,000 light-years.
