Pictured is M31's companion galaxy M32 . Little M32 is visible in most pictures of M31 - it is the small circular spot north of M31's center. M32 is a dwarf elliptical galaxy . Elliptical galaxies have little or no measurable gas or dust - they are composed completely of stars and typically appear more red than spiral galaxies . Elliptical galaxies do not have disks - they generally have oblong shapes and therefore show elliptical profiles on the sky.
