Presented by Dr Glen Mackie on 15th April 2011.

Galaxies have been observed from ultra high energy gamma rays to long wavelength radio waves, providing fundamental insights into their formation and evolution. Until now, astronomy atlases preferentially showed (only) optical images of galaxies. Unveiling the secrets of some of the best observed galaxies, the published MAG contains over 250 full colour images of 35 galaxies spanning the whole electromagnetic spectrum. MAG explains why we see the component stars, gas and dust via different radiation processes, and describes the telescopes and instruments used. The lecture will discuss the metamorphosis from a personal web site to an academic textbook, the author - publisher (Cambridge University Press) relationship, and highlights from the textbook.
