A spiral galaxy, seen partly from the side, with a messy, turbulent appearance. Its disc is made of multiple patchy arms that contain numerous sparkling blue and glowing red regions — star clusters and star-forming nebulae. Thick clumps of dark reddish dust swirl through the disc. The glow of the disc extends out into the dark background, where both distant and nearby stars can be seen.

A close-in view of a spiral galaxy that faces the viewer. Brightly lit spiral arms swing outward through the galaxy’s disk, starting from an elliptical region in its center. Thick strands of dark reddish dust spread across the disk, primarily along the spiral arms. The arms also contain many glowing, pink-red spots where stars form and clumps of bright-blue star clusters. Beyond its spiral arms, the galaxy is a bit fainter and speckled with blue stars.

A galaxy seen face-on, with a slightly elliptical disk that appears to have a hole in the center like a doughnut. In the hole, the core is a brightly glowing point that shines light out beyond the edge of the disk. Around the hole is an inner ring of dust, and at the galaxy’s edge is a thicker outer ring of dust, with a swirling web of dust strands in between. Blue stars and red nebulae are visible behind the dust.
