[M110 in Red, UA] [PNG]

The outer immediate companion of Andromeda (M31), M110 (or NGC 205) - the inner one is M32. Unlike most dwarf elliptical or spheroidal galaxies, it has recognizable dust clouds (two are visible here at about the 7 o'clock and 11 o'clock positions from the nucleus) and clear signs of recent star formation. This image shows a 9 arc minute section, seen in red light with the Lowell 1.1m telescope, focal reducer, and TI CCD. The nonlinear inensity mapping shows both the outer envelope and innermost bright, sharp nucleus.

From Bill Keel's image collection at the University of Alabama.

    [M110, NOAO]

    This picture of the Andromeda Galaxy's companion Messier 110 is a color composite of CCD images from the 0.9-meter telescope of the Kitt Peak National Observatory, near Tucson, Arizona. The peculiar dark structures, very probably dust clouds, are clearly visible in this short exposure image; due to these structures, M110 is often classified as E5p or E6p. Because of its small (linear) size, this galaxy is usually counted as a dwarf spheroidal or dwarf elliptical rather than a normal elliptical galaxy.
