mirror reflection: the glass lenses where producing a blurry image so they have been replaced by mirrors
Asked by Wiki User
A telescope must gather large amounts of light from a dim, distant object; therefore, it needs a largeobjective lens to gather as much light as possible and bring it to a bright focus. Because the objective lens is large, it brings the image of the object to a focus at some distance away

They are forming a picture based on sound waves arriving from a target in space, not an actual visual picture. They work better for determining what types of radiation is being emitted by the extraterrestrial object and conclusions can be made about it's makeup based on past data collected Check out the link provided for more information. Answer
Resolution on a telescope is determined by the wavelength of the light they use. The smaller the wavelength the better the resolution. The wavelength of radio waves can vary from a couple of metres to several kilometers long, so they do not give a clear image. Also they are forming a picture based on radio waves coming from a target many lightyears away, so there is often a big margin of error.

The reason people build larger Telescopes is because smaller telescopes have a smaller power to them, which results in less detail the farther they look. Larger telescopes use much larger lenses to see much farther and with much more clarity.
Asked by Wiki User
Telescopes in space produce better images than those on Earth because light and other radiation that is recorded by telescopes in space does not pass through the atmosphere, which could blur the image.

I am not so sure he was the first, but he is the most famous.

The main disadvantage of a gamma telescope is that the rays penetrate everything making it difficult to reflect them. The advantage is that they can view wavelengths outside of the Earth's atmosphere.

The main disadvantage of a radio telescope is the poor resolution of the images they obtain. This isn't due to a flaw in the design, but in a limitation of the radio signals they observe. The longer the wavelength of light (radio waves are light!) the fuzzier the image you receive.
In order to combat this, a larger telescope is needed. Radio telescopes are thus the largest astronomical telescopes, measuring hundreds of meters across (e.g. Arecibo radio telescope) or composed of many smaller dishes in large arrays of dozens of radio dishes (e.g. VLBA, Very Long Baseline Array).
Another disadvantage is the amount of human generated noise can easily interfere with the telescopes, and is harder to isolate and shield than from light pollution, as it easily reaches beyond horizons and around terrain and obstacles. This can require remote observation sites.
They also have many advantages, but that isn't the purpose of this question.

Currently, the radio telescope at Aricebo in Puerto Rica at 305 m diameter is the largest.
In hand are plans for a SKA telescope (see skatelescope.org) in the southern hemisphere. This enables our Milky Way galaxy to be studied. The total area of the many dishes will be 1 sq km, hence the name. The resolution of a radio telescope is determined by the length of the baseline, and in this case, South Africa, Australia and New Zealand are collaborators for the ground stations. There are intended to be several different types of aerials to cover a few hundred megahertz, out to a few thousand megahertz. Construction is expected to start in the near future.

Exactly the same way that an optical telescope gathers waves with wavelngths
shorter than radio waves:
Both the mirror of a reflecting telescope and the 'dish' of a radio telescope are
built to have the shape of a 'paraboloid' ... that's the solid shape you get when
you spin a parabola around its nose.
The paraboloid has the interesting geometric property that anything that comes
straight in, parallel to its axis ... whether it's bees, bullets, B-Bs, or electromagnetic
waves ... and bounces off the inside of the curve, all winds up at the same point,
called the "focus" of the paraboloid.
-- The focus is where the film, or the eyepiece, the CCD, or the spectrometer
of the reflecting telescope is placed. All the light that hits the whole mirror is
concentrated onto it.
-- The focus is where the radio receiver of the radio telescope is placed.
All the radio waves that hit the entire dish are concentrated onto it.
-- The focus is where the little LNB on the end of the arm that sticks out in front
of the TV dish on your neighbor's garage is placed. All the microwave waves
from the TV satellite that hit the entire dish are concentrated onto it.

It acts as a RADAR unit, sending radio waves and measuring the amount of time it takes for them to come back.
radio telescopes monitor radio signals from outer space. The signals are analysed and classified by type to determine the nature of the source and widen our knowledge of astrophysics and cosmology.
Asked by Wiki User
Optical telescopes use either lens' (refractory) or mirrors (reflective) to magnify light. Radio telescopes use dishes to pick up radio waves. sensors on the dishes collect the waves and turn them into a picture

Galileo Galilei put together his telescope in 24 hours in Padua after while he had about a Hans, a Dutch spectacle-maker, having invented a 3x spyglass which made objects seem near while on holiday in Venice. Galileo worked on things that had been said about this spyglass (which had been kept secret) and instinct. A few days later he produced an improved 8x version. He presented it in Venice it in early 1609, just months after Lipperchey's invention. Galileo's invention was named telescope by Giovanni Demisiani a Greek poet/theologian at a banquet of the Accademia dei Lincei in Aril 1609 form the Greek tele (far) and skopein (to see). Galileo continued to perfect his telescope until he produced a 33x model.

The Yerkes observatory (named after the Chicago Industrialist and street-car empire builder Charles Yerkes, who financed it) is the home of the world's largest telescope that uses a lens as the main light-gathering instrument. More recent large telescopes have used mirrors to gather the light, since large mirrors are far easier to make.

The Hubble Space Telescope was launched into orbit aboard NASA's space shuttle Discovery (mission STS-31) on April 24, 1990.
The Hubble Space Telescope was originally meant to be launched in 1986, but the explosion of the space shuttle Challenger delayed the launch until April 24th 1990.
The Hubble telescope is now seen as one of the most versatile telescopes in space. After it was launched in 1990, astronomers had a chance to change and improve the telescope through missions by astronauts aboard the Space Shuttle.

Telescopes, were essentially discovered in 1609. Galileo and later Keppler were the first astronomers to use them. They caught on rapidly as observing instruments and for look out purposes., it took the optician's a while to correct the inverted view on some of them, but once done, they took off.
