For what purpose are most telescope designed?
most telescopes are used to collect and focus on different types of electromagnetic radiation from stars. Including visible light
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 impact does light pollution have on astronomy?
No, it would not. Telescopes located on mountaintops ... above most of the atmosphere ... work much better than telescopes located in valleys do. And, viewed from the moon, where there's no atmosphere at all, the stars are plainly visible in the sky even when the sun is too.
Why do astronomers find it difficult to locate extrasolar planets with telescopes-?
Light from the stars they orbit makes it difficult to see them.
Does a nebula have no light of its own?
It does not have visible light of its own, that lite is provided by the shine of the stars in it and or around it.
What type of telescope uses visible light emitted by a star to make it seem closer?
"Optical" telescopes use visible light. But if they're used to observe stars, then their purpose is not to make the stars seem closer.
Why are visible-light telescopes normally put on high mountains?
In that case, there is less atmosphere to interfere with a clear view to the stars.
What is the difference between modern telescopes and galileo's telescope?
Galileo's telescope is what is called a refractory visible light telescope. It takes visible light and uses lenses to condense a lot of light down to what will fit into your eye. It was very rudimentary and could not see very much detail. Today, there are still refractory visible light telescopes. In fact, these are used by amateur astronomers to capture excellent pictures of the universe around us. They are limited in their aperture however (the size of the opening pointed toward the stars). There are many other kinds of telescopes now also. Reflecting telescopes can be much bigger. Currently, the largest are the Keck telescopes in Hawaii where there are two that have an aperture of 10 meters, where as Galileo's was only 10-25 mm. Besides visible light, we now use telescopes to see all the wavelengths of light, from radio waves through microwaves, infrared, ultraviolet, X-ray and gamma rays.

Reasons why astronomers have difficulty looking at distant stars except?
Light years of dust lanes obscure the view of distant stars in visible light. However, radio telescopes can penetrate the dust and can detect (in the x-ray and infrared spectra) the stars in the core of our galaxy.They don't understand how redshift affects stars.
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
What do telescopes do in order for us to see distant stars?
it collects light
What to telescopes do in order to let us see distant stars?
It collects light
How do you measure stars?
We use, in many remarkable ways, the [Spectrophic] Light obtained by telescopes.
Why don't we use visible-wavelength telescopes to locate neutron stars?
A neutron star emits most of its energy at higher frequencies.
Why there is no stars visible in Saudi Arabia jeddah?
Excessive light (light pollution), dramatically reduces the visibility of stars.
