Spiral galaxies form a class of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae and, as such, form part of the Hubble sequence. 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 are often … Ver mais Spiral galaxies may consist of several distinct components: • A flat, rotating disc of stars and interstellar matter of which spiral arms are prominent components • A central stellar bulge of mainly older stars, … Ver mais The Milky Way was once considered an ordinary spiral galaxy.
