Galactic Struggle Captured by Gemini Observatory
The Gemini Multi-Object Spectroraph on the Fredrick C. Gillett Gemini North Telescope on Mauna Kea in Hawaii captured this beautiful image of the ring galaxy NGC 660. The galaxy lies about 40 million light-years from Earth toward the constellation Pisces the Fishes. The field of view of the zoomed out image is 9.3×5.6 arcminutes. North is to the right and east is up. Total exposure for the image for all filters was 1,620 seconds. Credit: Gemini Observatory/AURA.
Strings of gas and dust, the wreckage of a colossal galactic struggle, lie strewn and littered about polar-ring galaxy NGC 660 in this new image from the Gemini Observatory.
Zoom around the ring of stars, stop to dive into massive star clusters and pink nebulae rich with the birth of new stars. Astronomers have found only a few of these bizarre objects. Most are made up of an early-type spiral galaxy, known as a lenticular galaxy, surrounded by a vast ring of stars extending for tens of thousands of light-years nearly perpendicular to the plane of the main galaxy. NGC 660, however, is the only polar-ring galaxy with a late-type lenticular galaxy as host.
