George
Hale
Geroge Hale
(1868 - 1938) was an American astronomer who is best
known for his work in solar astronomy. He is also
esteemed for his role
in founding some of the most important astronomical
observatories in the world.
In 1908, Hale made his most
influential discovery. Using a device called a
spectroheliograph (which he
invented), he observed that light from sun spots was altered
in ways that suggested that they were produced by powerful
magnetic fields.
He also helped found some of the
most
powerful observatories of
their time including the Mount Wilson Observatory, the
Palomar Observatory, and the Yerkes Observatory.
