A spiral galaxy.

Explanation:

This is a class of galaxy described in 1936 by the American astronomer Edwin Hubble.

The central bulge is characteristic of this type of galaxies, where the major concentration of stars resides. The "arms" are very bright and are full of young, blue stars.

The pinwheel shape is why we can easily recognize them from the earth. Astronomers think that more than 60% of the galaxies in the universe are spiral-like.
