George Ellery Hale (June 29, 1868 – February 21, 1938) was an American astrophysicist, best known for his discovery of magnetic fields in sunspots, and as the leader or key figure in the planning or construction of several world-leading telescopes; namely, the 40-inch refracting telescope at Yerkes Observatory, 60-inch Hale reflecting telescope at Mount Wilson Observatory, 100-inch Hooker ...
The observatory sits at the summit of 5,715-foot Mt. Wilson, accessible only by a serpentine stretch of Angeles Crest Highway. When George Ellery Hale established it in 1904 with funding from what ...
The Hale Telescope is a 200-inch (5.1 m), f / 3.3 reflecting telescope at the Palomar Observatory in San Diego County, California, US, named after astronomer George Ellery Hale. With funding from the Rockefeller Foundation in 1928, he orchestrated the planning, design, and construction of the observatory, but with the project ending up taking ...
The Kenwood Astrophysical Observatory was the personal observatory of George Ellery Hale, constructed by his father, William E. Hale, in 1890 at the family home in the Kenwood section of Chicago. [1] It was here that the spectroheliograph , which Hale had invented while attending MIT , was first put to practical use; and it was here that Hale ...
Astronomer George Ellery Hale, whose vision created Palomar Observatory, built the world's largest telescope four times in succession. [8] He published a 1928 article proposing what was to become the 200-inch Palomar reflector; it was an invitation to the American public to learn about how large telescopes could help answer questions relating to the fundamental nature of the universe.
The Hale Solar Laboratory is a historic astronomical observatory in Pasadena, Los Angeles County, California, United States.Built in 1923, it was the laboratory of astronomer George Ellery Hale (1868-1938), a pioneering figure in the development of the discipline of astrophysics in the United States.
The 69-inch (1.8 m) telescope at Perkins was immediately replaced with a 32-inch (810 mm) cassegrain reflector telescope. It was donated by Michael R. Schottland, an entrepreneur from Martinsville, Virginia. At that time it was the largest privately owned telescope in the United States. Currently it is one of the three largest telescopes in Ohio.
For the 60-inch telescope, George Ellery Hale received the 60-inch (1.5 m) mirror blank, cast by Saint-Gobain in France, in 1896 as a gift from his father, William Hale. It was a glass disk 19 cm thick and weighing 860 kg.
