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 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 ...
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 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 ...
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.
George Ellery Hale, then director of Yerkes, had the telescope brought to Mount Wilson to put it into service as a proper scientific instrument. Its 24-inch (61 cm) primary mirror with a 60-foot (18 m) focal length, coupled with a spectrograph, did groundbreaking work on the spectra of sunspots, doppler shift of the rotating solar disc and ...
The observatory, often called "the birthplace of modern astrophysics", was founded in 1892 by astronomer George Ellery Hale and financed by businessman Charles T. Yerkes. It represented a shift in the thinking about observatories, from their being mere housing for telescopes and observers, to the early-20th-century concept of observation ...
Griffith drafted detailed specifications for the observatory. In drafting the plans, he consulted with Walter Sydney Adams, the future director of Mount Wilson Observatory, and George Ellery Hale, who founded (with Andrew Carnegie) the first astrophysical telescope in Los Angeles. [5]
