Telescopes
A telescope is a device used to form images of distant objects. There are two kinds: an optical telescope uses lenses and is known as a refracting telescope or a refractor, and a reflecting telescope, which uses a mirror and is known as a reflecting telescope or a reflector. The earliest telescope was a refractor built by the Dutch eyeglass maker Hans Lippershey. This category is for questions related to telescopes, including using them to view distant planets and objects in space.

How many mm is the Emerson 50x100 Refractor Telescope with Tripod?
The Emerson 50x is 12mm and the 100x is 6mm.
How much did the SETI telescope cost?
They use many types of telescopes. You can probably pick up the cheaper ones for as little as $25,000. The Hubble Space Telescope cost $1,500,000,000 ($1.5 billion) just to build.
What is the limiting visual apparent magnitude of a 200 inch diameter telescope?
The limiting visual apparent magnitude of a 200-inch diameter telescope is around 27-28 magnitudes. This means it can detect very faint objects in the night sky, making it a powerful tool for astronomical observations.
What is inexhaustible energy resources that is used to power the Hubble space telescope?
Solar energy, all space equipment uses solar panels
How was the telescope successful?
The telescope, invented by Galileo in the early 1600's, allowed us to see objects better that were far away. Galileo is credited with using his first telescope to discover Jupiter's moons, Saturn's rings, and the craters and other features of our moon.
Why astronomers don't launch radio telescopes into space to make observations?
They are too big and heavy for it to be possible to launch them into space.
What type of telescope does not use optics?
Telescopes can be made to see in almost any part of the electromagnetic spectrum: visible light, infrared light, ultraviolet light, X-rays, or radio waves. The largest telescopes are those for radio waves - in Arecibo there is one with a diameter of 300 meters. I am not sure whether it is the largest, though.
What is the role of lenses used in cameras telescopes and microscopes?
In a simple microscope, a lens magnifies the image of the sample.
in a compound microscope, the objective lens magnifies the image (there may be more than one objective lens) and the eyepiece lens enlarges the virtual image (which is typically inverted by the objective lens).
Where is the hubble space telescope located?
The HST is located in space. It flies round the Earth once in 97 minutes; so the actual position is changing constantly.
How do you improve the resolution?
Get a bigger telescope. Resolution is proportional to the size of the telescope. But due to the atmosphere, there is a practical limit beyond which it makes no difference what the telescope size is.
What are the numbers for the telescope on shrink ray island?
The coordinates for the school science room are 87 (left) and 16 (right).
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.
Why can radio telescopes be used 24 hours a day?
Unlike visible light waves, radio waves can penetrate through clouds.
What does the hubble space telescope look like?
From a distant viewpoint, the Hubble Telescope looks like a tiny dot. Coming up closer, it looks a little bit like a elongated cylinder covered in tin foil, similar to the cardboard core of a roll of toilet paper covered in tin foil, with wings (solar panels) attached to both sides.
What advantages does a radio telescope have over an optical telescope?
Quasars and some pulsars are dim in the visible light range. In the radio spectrum, however, they're extremely bright, and as such observing them in telescopes that observe these wavelengths is more beneficial.
How are radio telescopes different from keck telescopes?
Keck telescopes do not exist, Keck telescope refers to the WM Keck Observatory on Mt. Kea.
The Keck Observatory is comprised of several opticalreflecting telescopes, whereas a
radio telescope consists of a large parabolic solid metal or screen reflector with a radio
receiver at its focus, built to detect and measure radio waves.
What is the base line of a radio telescope array?
The distance between the two antennae that are the farthest apart is the baseline of a radio telescope array..
The creator of the telescope is hans lippershay, jacob metuis, and zacharias. They are all inventors of the telescopes. Hans lippershay is the origanal creator. He is the one that thought of the idea before any other people did.
He simply discovered many things that makes technology where we are!

In astronomy he used measurements made by Tycho Brahe to do many complicated calculations to discover the shape of the planets' orbits. The results were published as the three laws of planetary motion in 1618. They were found to give good results when used to predict the future positions of the planets. For this work Kepler is recognised as one of the founders of modern astronomy.
________________________________
Kepler worked with Tycho Brahe for several years. Brahe had no great skill in science or mathematics, but was a METICULOUS and precise observer. Based largely on Brahe's observations, Kepler was able to determine that the planet Mars - and by extension, all the other planets - traveled in elliptical paths under the influence of a force that was inversely proportional to the square of the distance between the Sun and the planet. This paved the way for Newton's development of calculus and the math that describes gravity.
Many people use a telescope. Astronomers, scientists, astronauts, cosmic data analysts. Even anyone who merely has a curiosity and wishes to know what is beyond our atmosphere uses a telescope.
Technically the shorter the focal length, the thicker the mirror. But some short focal length telescopes have relatively thin mirrors all the same.
