What sort of telescope is the Hale telescope, and how does it work?
- The Hale Telescope is named after the astronomer Hale. A 200-inch (5.1-meter) f/3.3 reflecting telescope at the Palomar Observatory in California, United States, named for astronomer George Ellery Hale, it is the world’s largest telescope. With money from the Rockefeller Foundation in 1928, he supervised the planning, design, and building of the observatory, although the project ultimately took more than a decade to complete.

What does the Hale Telescope study?
A workhorse of modern astronomy, the 200-inch Hale Telescope was dedicated in 1948 and was the largest effective telescope in the world until 1993. It contributes to a wide range of astronomical research, including Solar System studies, the search for extrasolar planets, stellar population and evolution analysis, and the study of galactic structure and evolution.
What tolerance is the primary mirror on the Hale Telescope polished to?
The 200-inch-diameter mirror that would be at the center of the massive telescope George Hale envisaged would be machined and polished to a paraboloid shape with a tolerance of millionths of an inch or better.
What discoveries did the Hale Telescope make?
Palomar Observatory is named after George Ellery Hale, an astronomer who lived in the nineteenth and twentieth centuries and is renowned not just for his scientific achievements — he discovered, for example, that magnetic fields and sunspots are connected — but also for his financial acumen.
What type of image is formed by a reflecting telescope?
Because it is an upright picture, the image created by a reflecting telescope is a close up view of the object.
Who built the Hale Telescope?
The astronomer George Ellery Hale built the world’s biggest telescope four times, each time outdoing the previous one in size. Palomar was the pinnacle of his professional accomplishments.
How long did it take to build the Hale Telescope?
More than 14,000 pounds (4.5 tons) of glass was crushed and polished away over a 13-year period, decreasing the weight of the mirror from 21.5 to 14.5 short tons (13.2 t).
How much does the Hale Telescope weigh?
The telescope was named in honor of the eminent American astronomer George Ellery Hale, who oversaw the design of the device and was instrumental in its construction. The primary mirror of the Hale Telescope is 5 metres (200 inches) in diameter and weighs 14.5 tons, making it the largest telescope in the world.
Who built Mt Palomar Observatory?
The construction of Palomar Observatory was overseen by George Ellery Hale, who was the primary architect. He was a graduate of MIT and the founder of Caltech, and in 1928 he was awarded a $6 million grant from the Rockefeller Foundation to fund the construction of a 200-inch reflecting telescope at the institute.
How big is the Hale Telescope?
For 45 years, the 200-inch (5.1-meter) Hale Telescope (f/3.3) was the most powerful effective telescope in the world (1948-1993). It continues to be a workhorse in the field of contemporary astronomy. This facility is utilized every night for a wide variety of astronomical investigations.
What kind of light is the VLA used for?
Answer: The VLA, as well as all radio-wavelength telescopes, capture information from the portion of the electromagnetic spectrum that corresponds to radio frequencies. Remember that “light” is also derived from the same electromagnetic spectrum, but it originates from a higher-frequency end of this spectrum of energy rather than the lower-frequency end.
How does a reflecting telescope gather light?
Why Mirrors Are More Effective A reflecting telescope is a type of telescope that makes use of mirrors to magnify light. The light is intensified as a result of the reflection off of the mirror. So all that is required is for the mirror to have the appropriate curved form. In comparison to making a huge, near-perfect mirror, making a large, near-perfect lens is far more difficult.
What type of light does a radio telescope use to study the universe?
A radio telescope is a type of radio receiver that is used in astronomy to receive radio signals. Instead of seeing visible light like a “ordinary” telescope, a radio telescope “sees” radio waves radiated by radio transmitters, generally through the use of a large parabolic (“dish”) antenna or arrays of parabolic antennas.
What type of mirror is used in reflecting telescope?
The Primary Objective of the Reflecting Telescope or Reflector is a concave mirror, rather than a lens or lenses, which is used to focus the light entering the telescope. The kind of reflector is determined by the other system mirror(s), which are referred to as the Secondary Mirror.
