What did George Ellery Hale discover?
George Ellery Hale using the spectrograph in the 60 foot solar telescope, where, in 1908, he discovered magnetic fields on the Sun, the key to understanding sunspots and solar weather. The 60-inch saw first light in December 1908, but Hale was already pursuing bigger goals.
Why does Mulder use George Hale?
George Hale was the visionary behind the Palomar Observatory in California. Mulder explained this to Scully in the past episode The X-Files: Little Green Men (1994), where he also used it as an alias for his flight to Puerto Rico.
How big is the diameter of the massive Mt Palomar reflecting telescope?
1947: After 13 years of grinding and polishing, the Palomar Observatory mirror is completed at Caltech. It was, at the time, the largest telescope mirror ever made in the United States, measuring 200 inches in diameter.

How does the Hale Telescope work?
The Hale Telescope uses a special type of equatorial mount called a “horseshoe mount”, a modified yoke mount that replaces the polar bearing with an open “horseshoe” structure that gives the telescope full access to the entire sky, including Polaris and stars near it.
Who built the Hale Telescope?
Astronomer George Ellery Hale
Astronomer George Ellery Hale built the world’s largest telescope four times over, each new instrument trumping the last. Palomar was his crowning achievement.
Who operates Hale Telescope?
California Institute of Technology
Conceived of by astronomer, George Ellery Hale, (1868-1938), and owned and operated by the California Institute of Technology (Caltech) research partners include the Jet Propulsion Laboratory (JPL) and Cornell University. The observatory operates several telescopes, including the famous 200-inch (5.1 m) Hale Telescope.

What was the problem with the Hale Telescope?
The Hale’s 200 in (510 cm) mirror was near the technological limit of a primary mirror made of a single rigid piece of glass. Using a monolithic mirror much larger than the 5-meter Hale or 6-meter BTA-6 is prohibitively expensive due to the cost of both the mirror, and the massive structure needed to support it.
