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 kinds of telescopes are used to see stars in visible light?

Refracting telescopes and reflecting telescopes are commonly used to observe stars in visible light. These telescopes utilize lenses or mirrors to gather and focus light, allowing astronomers to view stars with clarity and detail.


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.

Can you study visible light using a radio telescope explain your answer?

No, a radio telescope is designed to detect radio waves, which have much longer wavelengths than visible light. Visible light cannot be studied using a radio telescope as it operates in a different part of the electromagnetic spectrum. To study visible light, astronomers typically use optical telescopes.


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 do most telescopes collect and focus?

Most telescopes collect and focus light from distant objects in space, such as stars, planets, and galaxies. This focused light is then magnified and analyzed by astronomers to study and make observations about the universe.


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 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.


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.


Which form of energy are optical telescopes used to study?

Optical telescopes are used to study electromagnetic energy in the form of visible light. This allows astronomers to observe and study objects in the universe, such as stars, planets, galaxies, and other celestial bodies that emit or reflect visible light.
