M31, GALEX
The spiral galaxy M31 is the nearest example of this kind of galaxy. It is inclined to our line of sight so that we can see structure in the spiral arms as well as the central bulge. Observations of galaxies like these can help us determine the structure of our own Galaxy, the Milky Way.

This image shows M31 as seen by the Galaxy Evolution Explorer (GALEX), an ultra-violet telescope orbiting the Earth at a height of 690 kilometers (428 miles). This is a two colour image: blue corresponds to higher enegy UV photons which trace young stars in the spiral arms, red traces lower energy photons from older stars in the central bulge.
