Otherwise it won't remain pointed at the same spot in space any longer.
because of the earth's rotation _________________________________________________________________________________ To continuously observe an object directly above the horizon at all times, telescopes must be able to move.
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.
Otherwise it won't remain pointed at the same spot in space any longer.
Astronomers move their telescopes to track celestial objects as they appear to move across the night sky due to the Earth's rotation. This motion allows for continuous observation and data collection without losing sight of the target. Additionally, positioning telescopes in different locations can help minimize atmospheric interference and light pollution, enhancing the quality of observations.
The earth turns on its axis; it orbits around the earth-moon barycenter; it orbits around the sun.
because earth turns around and around that it takes 24 hours the Sun doesn't move
The interior of the earth is molten.
If you ask how, it spins in circles. It turns fully in about one month, I believe:)
whenever nasa or whoever ae able to send people to mars
Yes. It takes energy to move them in the correct direction. In home telescopes, this is done by hand (energy from your muscles), in large telescopes they use some kind of motors to do that.
i really don't know actually to be honest
The sun continues to move across the sky, during the daylight hours, as the earth turns, no matter if the sky is clear or cloudy.
