Exploring the Southern sky

On the occasion of its 25th anniversary the European Sou- thern Observatory (ESO), is publishing a selection from its photographic treasures of the southern skies: 90 colour and 147 black and white plates have been reproduced. Thirty maps make it easy to locate the objects shown. Part 1 is devoted to extragalactic phenomena. Part 2 deals with our Galaxy. Part 3contains the results from observations of minor bo- dies in the solar system(asteroids and comets with an em- phasis on the most beautiful Halley's comet photographs). The final part presents the Observatory itself.
