To compensate for the motion of the Earth in order to observe a fixed object, such as a distant star. Relative to the Earth, distant objects do not move, but the Earth rotates and orbits the sun, thus all objects appear to move relative to a fixed point on the Earth. Therefore telescopes (which are fixed points) must move to compensate for this motion.

Did ancient Egyptian astronomers have telescopes?
No, ancient Egyptian astronomers did not have telescopes. They relied on naked-eye observations of the sky and developed impressive astronomical knowledge and calendars based on these observations. Telescopes were not invented until much later in history.
How do I use lenses in a sentence?
Lenses can help people to see better. Lenses are needed in telescopes for astronomers to see distant things in the night sky.
Why are telescopes in deserts?
Telescopes are often located in deserts because deserts offer very dry and clear atmospheric conditions, which are ideal for observing celestial objects. The dry air minimizes atmospheric distortion, providing astronomers with clearer and more detailed images of the night sky. Additionally, deserts have fewer artificial lights, reducing light pollution that can interfere with astronomical observations.
What tool do scientists use to observe stars?
In earlier times, scientists primarily relied on sky gazing to observe heavenly objects. Later telescopes were made use of. Today we have a huge network of telescopes based both on earth and its orbit constantly observing the sky.
Why do astronomers currently prefer orbiting telescopes over earth based telescopes?
Orbiting telescopes are located in the sky, where it is not affected by the turbulence of the atmosphere, while ground-based telescopes are located on the ground, where the atmospheric turbulence (the moving of air) is greater. This is also the reason that some telescopes are built on mountains where the atmosphere is thinner and turbulence is smaller.
Used to see stars and planets?
A telescope is used to see stars and planets by collecting and magnifying light from distant objects in the night sky. Telescopes come in different types such as refracting, reflecting, and compound telescopes, each with its own advantages for observing celestial bodies. Professional astronomers and amateur stargazers alike use telescopes to explore the universe and observe objects like galaxies, nebulae, and planets in detail.
Why are radio telescopes able to operate all the time?
That is because radio waves pass through clouds so radio astronomers do not have to wait for a clear sky.
Why do observatories have dome that can opened and turned?
Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened during observing, and closed when the telescope is not in use. In most cases, the entire upper portion of the telescope dome can be rotated to allow the instrument to observe different sections of the night sky. Radio telescopes usually do not have domes.
How do astronomers study the movement of stars in the night sky?
Astronomers study the movement of stars in the night sky using telescopes and specialized instruments to track their positions and trajectories over time. By observing and analyzing the patterns of star movements, astronomers can gain insights into the dynamics of the universe and the behavior of celestial objects.
Why do astronomers currently prefer orbiting telescopes over earth-base telescope?
Orbiting telescopes are located in the sky, where it is not affected by the turbulence of the atmosphere, while ground-based telescopes are located on the ground, where the atmospheric turbulence (the moving of air) is greater. This is also the reason that some telescopes are built on mountains where the atmosphere is thinner and turbulence is smaller.
Astronomers can see planets because planets they?
reflect light from the sun, making them visible in the night sky. By observing the way a planet moves and changes position relative to the stars, astronomers can track its orbit and study its physical characteristics. Telescopes and other advanced technology help astronomers gather more detailed information about planets in our solar system and beyond.
