    a spiral galaxy is simply I I0 = e−r/rd (7.01) where I0 is the galaxy’s central surface brightness in units of ergs cm−2 s−1 arcsec−2 and r d is the scale length of the expo-nential. However, not all spiral galaxies have a bulge, and in some galaxies (such as M31), a de-composition into a de Vaucouleur bulge plus an exponential disk

    Spiral Galaxies are the most famous type of galaxy. They typically consist of a central bulge, a disk on the same plane as the bulge and a halo which surround the galaxy. Spiral galaxies are so named for the spiral structures which extend from the galactic bulge. Some spiral galaxies, such as the Milky Way, have a central bar which extends from the bulge. Roughly 2/3 of all

    A barred spiral galaxy is a spiral galaxy with a central bar-shaped structure made of stars. Bars are found in up to 65% of spiral galaxies. They effect the motions of stars, dust and gas. It is believed that bars act a bit like a funnel, pulling matter into the bulge from the disk

    Spiral galaxies—of which the Milky Way system is a characteristic example—tend to be flattened, roughly circular systems with their constituent stars strongly concentrated along spiral arms. These arms are thought to be produced by traveling density waves, which compress and expand the galactic material

    Oct 20, 2019 Spiral galaxies are among the most beautiful and plentiful galaxy types in the cosmos. When artists draw galaxies, spirals are what they first visualize. This is likely due to the fact that the Milky Way is a spiral; as is the neighboring Andromeda Galaxy. Their shapes are the result of long galactic evolution activities that astronomers are still working to understand

    A spiral galaxy is a kind of galaxy that looks like a flat, slowly rotating disk with a bulge in the centre, and spiral patterns extending outward from the bulge. It contains stars, gas, dust, dark matter and a supermassive black hole at its centre. Galaxies were long thought to be nebulae.The spiral nebula as a type was first described by Edwin Hubble in his 1936 work
