Explorers Club

The Explorers Club is an international multidisciplinary professional society dedicated to the advancement of field research and the ideal that it is vital to preserve the instinct to explore. Since its inception in 1904, the Club has served as a meeting point and unifying force for explorers and scientists worldwide. Our headquarters is located at 46 East 70th Street in New York City. Founded in New York City in 1904, The Explorers Club promotes the scientific exploration of land, sea, air, and space by supporting research and education in the physical, natural and biological sciences. The Club's members have been responsible for an illustrious series of famous firsts: First to the North Pole, first to the South Pole, first to the summit of Mount Everest, first to the deepest point in the ocean, first to the surface of the moon--all accomplished by our members.

  • The Hubble Space Telescope and the Visionaries Who Built It

    Mon, Jun 30, 2008
    **The Hubble Space Telescope** has produced the most stunning images of the cosmos humanity has ever seen. It has transformed our understanding of the universe, about its age and evolution, the life cycle of stars, and the very existence of black holes. The Hubble was designed after World War II, when astronomer **Lyman Spitzer** and a handful of scientists waged a fifty year struggle to build the first space telescope capable of seeing beyond Earth's atmospheric veil. **Robert Zimmerman,** author of *The Universe in a Mirror: The Saga of the Hubble Space Telescope and the Visionaries Who Built It*, takes us behind the scenes, explaining how some of Hubble's advocates sacrificed careers and family, and how others devoted their lives to the telescope only to have their hopes and reputations shattered when its mirror was found to be flawed. Zimmerman is an award-winning science writer and historian whose work has appeared in *Natural History*, the *Wall Street Journal* and *Astronomy*, among other leading publications.
