Upon closer inspection, you may find that the spiral galaxy actually looks like a pinwheel, with its arms going out from the central cluster of stars. The central bright region at the core of a galaxy is called the "galactic bulge". Astronomers can detect this movement because the light coming from Messier 90 is skewed toward the blue. There are many different examples of galaxies that are spirals, including the Triangulum Galaxy, the Whirlpool Galaxy and the Pinwheel 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. This is due to the fact that the Milky Way is a spiral galaxy. A spiral galaxy typically has a rotating disc with spiral 'arms' that curve out from a dense central region. The large stars of a spiral galaxy do not last very long because they are constantly burning large amounts of fuel. As the circular motion of the galaxy continues, the outer stars would naturally form arms because of the slower rotating motion compared to the stars found in the middle. Spiral galaxies have lots of gas and dust which means it has younger stars. As of 2005, the Milky Way galaxy has been classified as a Barred Spiral Galaxy. We have the bulge.
