Spiral Galaxies
(page 1)
Spiral galaxies are rotating disk systems of stars, gas and dust. Due to their varying orientations in the sky, they may appear as face-on whirlpools, edge-on disks, or as something in between. Spirals are classified based on the tightness of their arms the size and shape of their nucleus. Those with an elongated bar-like center are called "barred spirals."
