Polar-ring Galaxy NGC 660 in Pisces | Subaru Telescope
NGC 660 is a polar ring galaxy located in the constellation Pisces. It features a large, extended ring structure surrounding the central spiral galaxy at a near-perpendicular angle. NGC 660 spans about 40,000 light years across. The ring emits blue light from active star-forming regions within it. The dark lanes in the ring and the galactic disk intersect, highlighting its complicated structure. This ring structure is thought to have been formed through the gravitational interaction of the central galaxy with another galaxy.
Distance from Earth: ~40 million light-years
