What are the 4 great observatories?
Great Observatories, a semiformal grouping of four U.S. satellite observatories that had separate origins: the Hubble Space Telescope, the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.
Where are most ground-based observatories located?
Almost all of the world’s finest ground-based observatories are located on mountains, for a variety of reasons. First and foremost, starlight appears less distorted in the thin atmosphere on mountaintops.

What is the 4th and last satellite of NASA’s Great Observatory program?
Chandra will increase our understanding of the origin, evolution, and destiny of the universe. The Spitzer Space Telescope represents the fourth and final element in NASA’s Great Observatory program. The Spitzer Space Telescope was launched into space by a Delta rocket on August 25, 2003.
Why are major observatories place high on mountaintops or in space Name two major observatories?
Most important, putting an observatory on a mountaintop means there’s less air to see through, so the “seeing” is better. On a mountaintop, there’s also less air above you to absorb light from the stars.
Why are major observatories place high on mountaintops or in space?
The reason large telescopes are built on tall mountains or put in space is to get away from the distortion of starlight due to the atmosphere. Because of the elevation, the telescopes are above most of the water vapor in the atmosphere, so infrared astronomy can be done.
Where are the biggest observatories in the world?
Keck Observatory, astronomical observatory located near the 4,200-metre (13,800-foot) summit of Mauna Kea, a dormant volcano on north-central Hawaii Island, Hawaii, U.S. Keck’s twin 10-metre (394-inch) telescopes, housed in separate domes, constitute the largest optical telescope system of the burgeoning multi- …
What kind of telescopes do observatories use?
Two major types of telescopes dominate astronomy: reflectors and refractors. Many of the world’s largest telescopes are housed at observatories: The entire complex of buildings, telescopes, equipment, and staff involving scientific astronomical observations.
How far can a ground-based telescope see?
The farthest that Hubble has seen so far is about 10-15 billion light-years away. The farthest area looked at is called the Hubble Deep Field.
What type of telescopes are used in observatories?
