A spiral galaxy is a galaxy consisting of a rotating disk of stars, gas and dust which has a number of arms extending outwards from the galactic centre. Some spiral galaxies have a prominent bulge around the centre, while others have a bar crossing the centre with the spiral arms extending from the ends of the bar.
Some Creation scientists have argued that spiral galaxies are evidence of a young universe.
The Milky Way is a spiral galaxy, as is the Andromeda galaxy, the closest large galaxy to the Milky Way.
