Here's NGC 3628, also known as the Hamburger Galaxy, an unbarred spiral galaxy about 35 million light-years away in the constellation Leo. Its most conspicuous feature is the broad and obscuring band of dust located along the outer edge of its spiral arms, effectively transecting the galaxy to the view from Earth.
