From the sides of the oval emerge two bright spiral arms which wind through the round disk of the galaxy, filled with shining pink spots where stars are forming and more dark reddish dust. Many stars are visible in the foreground, over and around the galaxy.

Its disk holds many bright red spots where stars are forming, dark reddish threads of dust that obscure light, and bluish glowing areas that hold concentrations of older stars. It has a large, glowing yellow oval area at the center, from which two spiral arms wind through the galaxy’s disk. One side of the disk appears rounded (bottom of the image) while the opposite side appears somewhat squared-off (top of the image).
