Spiral galaxies are named for the (usually two armed) spiral structures that extend from the centre into the disk.
The spiral arms are sites of ongoing star formation and are brighter than the surrounding disk because of the young, hot stars.

∙ 8y ago-here are some more characteristics on spiral galaxies- Some spiral galaxies appear to have a bulge in the middle and arms that outward,like pinwheels. Such galaxies are called spiral galaxies. The spiral arms contain many bright, young stars as well as gas and dust. Most new stars in spiral galaxies form in these arms. Relatively few new stars are forming in the central bulge.
