NGC 5172 is a spiral galaxy containing more than a 100 billion stars, along with vast clouds of gas and dust. Within a thin disk, the spiral arms exhibit a pinwheel structure. Along the spiral arms, dark dust clouds collapse to create star-forming regions, leading to bright clusters of new stars. Spiral galaxies can be both colorful and majestic.
