Caption: This galaxy, NGC 4565, is a disk galaxy viewed at nearly an edge-on angle. The darker line running down the middle of the disk is a feature called a dust lane, identified by users in the Galaxy Zoo 2 project. Dust in galaxies can act as shadows, absorbing the starlight from the center of the galaxy and showing up as a dark feature. Galaxies like these are of particular interest for their links to star formation and the speeds at which galaxies rotate.
