Telescopes cannot detect?
Telescopes can not detect any radiation for which they were not specifically built. For example, a radio telescope is specifically designed to detect radio waves. Also, telescopes can not detect radiation that is too faint for them. What is too faint depends on the capabilities of the telescope.
How many refracting telescopes are there in the world?
to answer your question there are four categories of telescopes (1) optical telescopes: it uses concave mirrors in reflecting telescopes and they were created to collect light and be used to view distant objects by using the light to form the image. (2) radio telescopes: they are used to detect energy in the visible spectrum(light)and they also detect energy that has been emitted in wavelengths across the electromagnetic spectrum and can prove that some of the energy emits more non-visible radiation (radio waves) than the others, they are mostly used at night but for some certain areas they are used to understand different reactions during the day. (3) infrared telescopes: they are used to collect and photograph Infrared radiation to provide a complex type of map (heat map) to help study an object or area under investigation. (4) telescopes in space: collecting information using telescopes on earth, wether they are optical, radio or infrared are all subject to a degree of interference by the atmosphere which is why astronomers commonly use telescopes out side the earths atmosphere because of the minimal interference. An example of one is the Hubble space telescope launched in 1990 by NASA and two months later it was discovered that the telescopes mirror had been ground to flat and would not focus sharply. In 1994, after 30 hours of space walks by 5 astronauts, ten button-sized mirrors were installed to remedy the fault. A resolution 10 times better than that of any telescope on Earth was achieved. hope this thoroughly answered your question and the extra info is just for a further understanding of telescopes thanks for referring to my answer made by D.F
What do scientists build telescopes on top of?
Some telescopes are on the earth this is because they are easier to maintain as it does not require launches to get astronaughts up there to fix them. Also they are cheaper having to make a telescope usable in space takes time and money, it also requires a launch which is expensive as well. It is easier to view the results as you can view them directly from the telescopes, instead of them having to be sent from space down to earth using microwaves then you need an antenna and other.
Why have no large refracting telescopes been built since 1900?
Refracting telescopes suffer from chromatic aberration, refracting telescopes have several surfaces to shape and polish, making large glass lenses without interior defects is very difficult, and large glass lenses are more difficult to support than large mirrors.
Why are most large telescopes reflecting telescopes?
They are refracting telescopes(:Large refracting telescopes are no longer built because there were too many problems with them. There was color distortion, light pollution, and when the object hits the focal point it turns upside down. Then you don't see the object for what it really is, you see it upside down and weird-ed out. They are to complicated and scientists believed they should just stick with the simple, small, original refracting telescopes!!!!-Meghan Betts (8th grader)
Why aren't infrared telescopes built at low altitudes where they would be easier to get to?
Carbon dioxide and other greenhouse gases are opaque to infrared radiation, therefore the less atmosphere there is for an infrared telescope to look through, the more you will be able to see.
Why are large telescopes built up in remote areas?
Because there is less atmospheric distortion at higher altitudes, and light pollution is avoided.
Is it true that scientists are currently building an infrared telescope?
Yes. There have been many infrared telescopes built, deployed on the ground, launched by balloon, carried on aircraft, rockets, and in orbit.
Who built telescopes?
isac newton and galileo galilei
Who built and used reflecting telescopes?
Thousands of people still do build their own astronomical telescopes; it isn't that hard to do.
Why arent the twin towers being built again?
They are being built again.
What are observatories?
An observatory is a location used for observing terrestrial and/or celestial events. Astronomy, climatology/meteorology, geology, oceanography and volcanology are examples of disciplines for which observatories have been constructed. The term is usually applied to astronomical observatories that have one or more large telescopes. Optical telescopes have been built at higher altitudes to avoid atmospheric interference. The Hubble Space Telescope is an orbital observatory launched in 1990.
Why do astronomers currently prefer orbiting telescopes over earth based telescopes?
Orbiting telescopes are located in the sky, where it is not affected by the turbulence of the atmosphere, while ground-based telescopes are located on the ground, where the atmospheric turbulence (the moving of air) is greater. This is also the reason that some telescopes are built on mountains where the atmosphere is thinner and turbulence is smaller.
Why have astronomers built the largest visible light telescopes on the tops of mountains?
in california iguusses
What are some good telesconpes that have built in cameras?
The best telescopes with built in cameras are made by Samsung and Sony. They are difficult to find and should be purchased from the internet.
