Spiral Galaxies
Spiral galaxies, which number about half of all galaxies, show a disk-like distribution of matter, in which the youngest, brightest stars outline the distinctive spiral arms. Spiral galaxies are characterized by elongated spiral arms and a central bulge. There is quite a range of variability in size, shape, and aspect ratio of arms/bulge. The Milky Way is a spiral galaxy.
Here is a picture of a spiral galaxy (the Messier 51 or Whirpool Galaxy) seen face on with respect to us. This galaxy has also a baby galaxy attached to it (right hand side).
The image above is of a spiral galaxy, NCG4565, seen edge on.
