NGC 660

"This Gemini North telescope image captures the “bloody” aftermath of one galaxy piercing the heart of another. All the action appears in a single frame, with the stunning polar-ring galaxy NGC 660 as the focus of attention. NGC 660 spans some 40,000 light years across and lies about 40 million light years distant in the direction of the constellation of Pisces. It has an unusually high gas content and resolves into hundreds of objects, a considerable fraction of which are blue and red supergiant stars. The ring’s youngest detected stars formed only about seven million years ago, indicating a long and ongoing process of formation. As NGC 660’s ring is not truly polar, but inclined ~45˚ from the plane of the disk, it most likely formed by a previous interaction with a gas-rich galaxy about a billion years ago. That event would have stripped the interloper of its gas, directed it into NGC 660’s core, and triggered a furious burst of star formation. When the resulting short-lived, massive stars exploded shortly thereafter as supernovae, they would have generated shock waves that triggered more star formation, and so on, even to this day. " This image of the ring galaxy NGC 660, obtained with the Gemini Multi-Object Spectrograph on the Fredrick C. Gillett Gemini North telescope was obtained in August of 2012. The image is made from three images taken through g, r, i, and hydrogen alpha filters and assigned the colors of blue, green, orange and red respectively in this color composite image. The field of view is 9.3x5.6 arcminutes and it is oriented 8 degrees clockwise from north at right and east up. The total exposure (integration) time is 1,620 seconds for all filters. Color composite produced by Travis Rector, University of Alaska Anchorage.
