Why do astronomers have to stay awake all night to use visible light telescopes?

Because the visible light coming from the stars is so faint that during the day the light form our local star (the Sun) is so bright that it swamps the starlight.
Thus to make observations using visible light, astronomers have to do so at night.

What instrument to astronomers use?
They use telescopes, but different types of telescopes. There are telescopes for radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays, all depending on what it is you're trying to see.
What kinds of telescopes are used to see stars in visible light?
Optical telescopes.
Why can't astronomers study the central regions of the Milky Way Galaxy using optical visible-light telescopes?
That's because they wouldn't see anything. There is too much dust interfering with light in that region.
What telescope does not use visual light energy?
Radio telescopes and infra-red telescopes operate at longer wavelengths/lower frequencies than visible light. Ultraviolet telescopes operate at shorter wavelengths/higher frequencies than visible light.
Why astronomers study radiation beyond the violet end of visible light and beyond the red end of visible light?
Astronomers study as much of the spectrum of radiation as they can, and the visible spectrum is only a small segment of it.
Why have astronomers built the largest visible light telescopes on the tops of mountains?

What are the largest telescopes used for observations in the visible region of the spectrum?
The largest telescopes that use visible light are reflector telescopes.

Do astronomers spend all their time looking through a telescope and recording their results?
Nowadays, the bulk of the work astronomers do is on computers. They spend a small portion of their time at telescopes actually taking data. Astronomically-useful telescopes rarely have eyepieces you can look through. Radio, ultraviolet, or infrared telescopes collect light that you can't even see with your eye! Telescopes that collect visible light often have electronic cameras called CCD cameras that create an image in a computer. Many telescopes are used to create a spectrum (the light is split into a rainbow, and the brightness of each color is measured). Radio telescopes record signals that astronomers can reconstruct using a computer to make an image or a spectrum.
What do astronomers use to measure stars?
Their eyes, Refracting Telescopes (ones with class lenses) Reflecting Telescopes (ones with mirrors) Radio Telescopes Imaging computer chips in conjunction with telescopes Space based telescopes Underground telescopes (to detect high energy or exotic particles from stars) Gravity wave detectors

Why are radio telescopes not located on top of mountains like the visible light telescopes?
It is not necessary to do so, as atmosphere doesn't distort radio signals as much as visible light.
How radio telescopes differ from optical telescopes.?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
What are light telescopes?
Telescopes that work with visible light, as opposed to other radiations such as infrared, ultraviolet, x-rays, etc.
What telescope does not use visual light energy?
Radio telescopes and infra-red telescopes operate at longer wavelengths/lower frequencies than visible light. Ultraviolet telescopes operate at shorter wavelengths/higher frequencies than visible light.
