When was the radio telescope first made?
The first radio antenna used to identify an astronomical radio source was one built by Karl Jansky, an engineer with Bell Telephone Laboratories, in 1931. Jansky was assigned the job of identifying sources of static that might interfere with radio telephone service.
Why does a reflecting telescope have no chromatic aberration?
There's no aberration with the main MIRROR of the telescope, because light doesn't go through the mirror. A reflecting telescope will have SOME chromatic aberration, because every reflecting telescope has at least one refracting lens; the eyepiece. Light goes THROUGH that lens, and light passing through the glass lens will generate some chromatic aberration.
What does a telescope reflect?
A reflecting telescope is an optical telescope which uses mirrors to bring the light to a focus. The first one was designed by Isaac newton.
What is the function of the dish in a radio telescope?
The shape is a paraboloid. In a paraboloid, all waves that come from infinity (or from far, far away - this is practically the same for the geometrical considerations) will be reflected in such a way that they gather at a single point.
How does a space telescope get lanched?
you lanch a space shuttle with the telescope in then i releses it that is the most basic way.
How is a radio telescope different from both a reflecting and reflecting telescope?
Well, its simple, there are two things that are in common.... both telescopes have a eye peice and a radio telescope doesnt.... theres more to it and the radio telescope looks way diffrent then the regular ones..... Wow! What a non-answer this person has given! For one thing, radio telescopes look more like satellite dishes than traditional telescopes. Rather than operating on the visible light spectrum as a reflecting or refracting telescope would, radio telescopes gather information from the infrared light spectrum - radiation waves. These radiation waves are collected to form a picture of whatever the radio telescope is looking at. I'm not a scientist; I'm not an astronomy student. I just did a little bit of research that the original answerer obviously didn't do.

How does a radio telescope gather radio waves?
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.
Who invented the radio telescope was it Karl Guthe Jansky or Grote Reber?
Grote Reber is the inventor of the radio telescope. He had searched extensively to find out about radio waves given off by the Milky Way Galaxy. He used parabolic reflectors for precise wavelength measures.
State the difference between optical and non-optical telescopes?
Optical measures visible light, Radio measures electromagnetic radiation in that part of the spectrum corresponding to radio waves. Same with X-ray telescopes and x-rays. Optical is the kind you look through.
Why can radio telescope can see things that a telescope that detect visible light cant?
-- The source may be one that emits electromagnetic energy in the radio portion of the spectrum but little or no visible light. -- There may be material in the way, such as dust or gas, that absorbs visible light but doesn't absorb radio energy.
Is a satellite dish a form of radio telescope or antenna?
A radio telescope gathers and focuses radio waves, or electromagnetic waves outside the visual spectrum. A satellite telescope is sent outside the atmosphere to become a satellite of either the earth or sun, unless it is sent outside the solar system like the Voyager spacecraft. Many satellite telescopes carry several types of telescopes in one package to gather as much information as possible, like the Hubble.
What does a refracting telescope do and how does it differ from other types of telescopes?
Ah, a refracting telescope is a wonderful invention! It works by using a lens to bend or refract light, helping us see objects in the distance with more clarity. Unlike other types of telescopes, like reflectors or catadioptrics, refracting telescopes use lenses instead of mirrors to gather and focus light. Remember, there's no right or wrong choice when it comes to telescopes – each one has its unique beauty and purpose!
Why doesn't the telescope mirror in a reflecting telescope get in the way of what you are viewing?
It does, a little. But the amount of light lost by the secondary mirror blocking the primary mirror is generally a small percentage. But to avoid even that loss, some reflecting telescopes are being built with an angled primary mirror. The secondary mirror is off-axis, meaning that the secondary mirror doesn't block ANY light from the primary.
What are some telescopes names?
The two types are refractor and reflector. In a refracting telescope, the light comes in THROUGH a magnifying LENS where it is REFRACTED (bent) to focus the light into an objective lens. In a reflecting telescope, the light BOUNCES OFF a curved magnifying MIRROR , and then reflected again on a secondary mirror to direct the light into an objective lens. Among the advantages of a reflecting telescope are that in a refracting lens, the thickness of the lens can absorb some of the light, while a mirror reflects all of the light. Additionally, a reflecting telescope can "fold" the telescope into a much more compact instrument, which is essential with especially large devices. A large refracting telescope would be enormously heavy and cumbersome.
