On this day, 100 years ago, George Ellery Hale observed the Sun's magnetic field from Mount Wilson in California for the first time.
“It was the first discovery of magnetic fields on the sun. It was the first discovery of magnetic fields anywhere off the earth,” said Edward Rhodes, a USC College professor of astronomy, who has been directing observations at the tower for more than two decades.
My alma mater, the University of Southern California, took over operation of Ye Olde Solar Tower in 1984, and it is still functional. Brilliant!
