In telescopes that use them, mirrors are the principal mechanism of magnification. The mirror is what gathers the light, and the more light gathered the better. The eyepiece is not the principal magnifier; the eyepiece serves to focus the gathered light so that it can make a clear image on the retina.
The larger the mirror, the more light is gathered, and the better the telescope is.

What are the practical uses for concave and convex mirrors?
Some practical uses for concave and convex mirrors are in medical instruments, car mirrors, and telescopes.
How long have humans used telescopes?
We know the telescope was invented by 1608 and soon many people, for example Galileo, were using telescopes. There is some evidence of earlier telescopes, but we aren't certain about that. So, humans have been using telescopes for about 400 years.
What function do mirrors serve in reflecting telescopes?
viewing objects lying above the eye level of the observer.
How are telescopes used in astronomy?
Telescopes are used to see things that are far away from earth. Using telescopes we can see things that are millions of miles away. Most of the telescopes are on Earth but some of them are in space such as the Hubble Space Telescope.
What design variants might one see in an optical telescope?
Some design variants you may see in an optical telescope include telescopes that fold or divert the optical path with mirrors and telescopes that use special lenses to enhance the images.
What are some negative impacts of using mirrors?
You see yourself.
Can mirrors cameras telescope and eye glasses refract light?
Mirrors don't refract, they reflect. All lenses, on the other hand, refract (bend) the light. All cameras have lenses, to focus the image; same for eyeglasses. Some telescopes have lenses, but others are collections of mirrors. Note that some few optical elements are lenses and mirrors - like prescription sunglasses with mirror coating.
What are some reasons you keep building larger and larger telescopes?
because the people of the world suck their dicks very hard
What are some ways that scientists are currently learning more about the solar system?
Scientists are currently using mirror telescopes in space that do not have to deal with light pollution and are more clear than lens telescopes to take pictures of the solar system. They are also using radio telescopes to try and discover extra terrestrial life.
Why are curved mirrors used in some telescopes?
Plane mirrors don't form real images. Concave mirrors and convex lenses do. Without a real image, you have nothing to expose film to, nothing to project onto a screen, nothing to capture on a CCD or vidicon, and nothing to look at with an eyepiece.
What type of telescope gathers radiation with a metal dish?
This best answer describes a reflecting telescope. The maximum size for a refractor on Earth is about 40 inches due to gravitational sag. Palomar's primary mirror is some 16 feet in diameter, and the Keck telescopes use several large mirrors that are computer-controlled and act as a single disk twice the size of Palomar.
Methods that are used to explore the universe?
The universe can be explored by astronomical instruments called telescopes, and by space probes sent from earth to other planets. When using telescopes astronomers try to look at the energy being produced by the universe not just in the visible part of the spectrum (where our eyes can see) but at the whole range of electromagnetic radiation. We thus have radio telescopes, infrared telescopes, X-ray telescopes and even some telescopes that are buried deep underground looking for neutrinos. Most of the telescopes are set in mountains for they can rich more.
