The Jewel on the Mountaintop
The European Southern Observatory through Fifty Years

Authored by ESO senior advisor Claus Madsen, the present book comprises 576 action-packed pages of ESO history and dramatic stories about the people behind the organisation. This is the ultimate historical account about ESO and its telescopes in the southern hemisphere, but also about a truly remarkable European success story in research. Spanning the range from the first telescopes to the future platforms of the next generation, it shows how the improvement of the telescopes leads to a continuously changing view of the Universe. With 150 photos and illustrations. Produced especially for ESO's 50th anniversary.
