Do optical telescopes allow us to study the visibal light radiated from stars?
Yes, optical telescopes are specifically designed to study visible light radiated from stars. They collect and focus visible light from stars to provide detailed images and spectra, allowing astronomers to analyze the properties of stars such as temperature, composition, and motion.
What are ultraviolet telescopes used for?
Ultraviolet telescopes are used to observe celestial objects emitting ultraviolet radiation, which is not visible to the human eye. They provide valuable information about the composition, temperature, and dynamics of stars, galaxies, and other astronomical phenomena that emit UV light. This can help astronomers study the formation of stars, the evolution of galaxies, and the presence of elements in the universe.
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.
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.
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.
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.
Do optical telescopes allow us to study the visibal light radiated from stars?
Yes, optical telescopes are specifically designed to study visible light radiated from stars. They collect and focus visible light from stars to provide detailed images and spectra, allowing astronomers to analyze the properties of stars such as temperature, composition, and motion.
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.

The visible part of distant galaxies is the galaxies'?
The visible part of distant galaxies is the collection of stars, gas, and dust within the galaxy. These components emit light that reaches our telescopes, allowing us to observe and study the structure and properties of the galaxies.

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 do telescopes do with electromagnetic radiation?
Telescopes collect and focus electromagnetic radiation, such as visible light or radio waves, to create images of objects in space. Different telescopes are designed to detect specific wavelengths of radiation to study various astronomical phenomena, from stars and planets to galaxies and black holes.
