König M., Binnewies S. The Cambridge Photographic Atlas of Galaxies

Cambridge University Press, 2017. — 351 p. — ISBN: 9781107189485.Galaxies - the Milky Way's siblings - offer a surprising variety of forms and colours. Displaying symmetrical spiral arms, glowing red nebulae or diffuse halos, even the image of a galaxy can reveal much about its construction. All galaxies consist of gas, dust and stars, but the effects of gravity, dark matter and the interaction of star formation and stellar explosions all influence their appearances.Spiral Galaxies
