Hale's most acclaimed scientific work was his demonstration that sunspots have strong magnetic fields. Hale's Polarity Law shows evidence of the existence of a well-organized large-scale magnetic field in the solar interior that cyclically changes polarity on average every 11 years.
May 11, 2018 · The American astronomer George Ellery Hale (1868-1938) designed and built three great observatories, invented the spectroheliograph, and discovered magnetic fields in sunspots. George Ellery Hale was born on June 29, 1868, in Chicago, Illinois, the eldest surviving son of William Ellery Hale and Mary Scranton Browne.
Jun 29, 2018 · Celebrating Caltech's Founder and Builder of Large Telescopes. June 29, 2018. When George Ellery Hale climbed Mount Wilson, a nearly 6,000-foot peak rising high above Pasadena, in 1903, he had a vision for building a new and bigger window to the cosmos.
