Spiral Galaxy Labeled, The scale bar is labeled in light-years along the top, which is the distance that light travels in one Earth-year. Globular Clusters A globular star cluster is a spherical group of up to a million stars held together by gravity. The image below shows a diagram I made of our own Milky Way galaxy – which is a spiral galaxy: The bulge of a spiral galaxy contains older stars while the spiral arms contain dust and newer, hotter stars and their associated hydrogen dust clouds (Universe, page 582). Spiral galaxies are surrounded by halos, mixtures of old stars, star clusters, and dark matter – invisible material that does not emit or reflect light but still has a gravitational pull on other matter. The image shows a scale bar, compass arrows, and color key for reference. Image C shows a (n) ELLIPTICAL GALAXY. Milky Way Galaxy: Side View Schematic illustration of the Milky Way galaxy, showing the prominent spiral arms, the central galactic bulge, the location of the Sun, and selected X-ray sources. Barred spiral galaxy UGC 12158 Spiral arms are regions of stars that extend from the center of barred and unbarred spiral galaxies. Astronomers have used observations from different telescopes to piece together our galaxy's May 5, 2026 · The spiral arms can be wound tightly or loosely, and some cannot be seen from Earth because we view the galaxy from the side, edge on. The Milky Way and the Andromeda Galaxy (M31) are two of a multitude of known spiral galaxies. nvfa, gv, ld, ht, 0jwz, xurqme, isx4hp, rmj0, nd9qyj4, nvnas5g,
