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. Spiral galaxies have three visible parts: a thin disk composed of stars, gas, and dust; a central bulge of older stars; and a spherical halo of the oldest stars and massive star clusters. Our Milky Way galaxy is a barred spiral galaxy, which means it has a bright line going through its center. Did you know that the Milky Way, our home galaxy, is a spiral galaxy?

Most spiral galaxies consist of a flat, rotating disk containing stars, gas and dust, and a central concentration of stars known as the bulge. These arms are made up of stars, gas, and dust, and they often contain regions of active star formation. Here, we delve deeper into ten fascinating facts about spiral galaxies, revealing their unique Supercomputing Reveals “Fossil Record” of Galaxy Collisions and Mergers Multimedia An example of a spiral galaxy, Messier 77 (also known as NGC 1068) Spiral galaxies form a class of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae[1] and, as such, form part of the Hubble sequence.
