Spiral galaxies have winding spiral arms that make them look a little like massive pinwheels.

These disks of stars, gas, and dust have bright bulges in their centers made up primarily of older and dimmer stars.

Their whirled arms are typically full of gas and dust, which helps give rise to the bright, younger stars visible throughout their length.

Spiral galaxies are actively forming stars and make up a large amount of all the galaxies in our nearby universe.

Spiral galaxies can be further divided into two groups: normal spirals and barred spirals. In barred spirals, a bar of stars runs through the central bulge of the galaxy.

The arms of barred spirals usually start at the end of the bar instead of the bulge. Our Milky Way is thought to be a barred spiral galaxy.
