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 often do you feed a telescope fish?
Different fish have different feeding requirements, but on average most fish can eat twice a day, small doses each feeding. A different food for morning and night is also recommended but not required. Such as flake in the morning and a frozen shrimp in the evening.

Does the Vatican have telescopes in Arizona?
Yes, the Vatican Observatory Research Group operates the Vatican Advanced Technology Telescope, one of the telescopes that is located at the Mount Graham International Observatory in Arizona.
What is the difference between a radio telescope and a light telescope?
radio telescope detects radio waves and a light telescope views light waves.
What problem does an earth - based telescope have that a space - based telescope does not have?
Atmospheric and environmental interference.
What exactly are collapsible water bottles?
They are water bottles that after they are not in use you can retract them. Think of a telescope if you would and how it extends, it is the same principle.
How is a radio telescope different from both a refracting and a 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.
Why do you send space shuttles to outer space?
Space shuttles are sent to outer space for several reasons, including scientific research, satellite deployment, and space exploration missions. They allow astronauts to conduct experiments in microgravity, service and repair satellites, and travel to the International Space Station. Additionally, space shuttles are used to advance our understanding of space and help pave the way for future space exploration.
What is needed to produce a telescope with high resolving power?
Mainly, it has to have a large main lens, or main mirror.
On Club Penguin how do you fix the telescope?
You stay at the ski hill and using your spy phone, click the wrench to the broken telescope arts. The wrench is found by pressing the red button on your spy phone.
How to determine the focal length of group of lenses?
Measure the distance from the center of the lens to the area where it 1.)Produces a clear image of very distant objects, 2.) The Sun (Be careful!), 3.) The Moon, 4.) A bright star or planet. The source needs to be at or near infinity. If you use a light source that is close to the lens, your results will not be accurate. Of course, if you know the F ratio, you have it! An F/2 lens will be twice the diameter of the lens. An F/10 will be ten times, etc.
If the focal lengths of the objective and eyepiece are equal,
then the magnification is ' 1 '.
Space Telescope such as the Hubble Space Telescope
Where is the Arecibo Observatory located?
The Arecibo Observatory is in the United States of America. It is in the municipality of Arecibo which is in Puerto Rico. It is a very famous radio telescope.
Who is the first man who study heavenly bodies using telescope?
I believe Galileo Galilei was the inventor of the telescope, which he then use to make observations about the heavens.
Kepler then refined these observations, which Sir Isaac Newton then condensed into the theory of gravitation of celestial bodies.
What is the biggest problem with building a giant refractor?
Grinding a lens to the required precision aw well as the mass of the lens distorting its shape.
In principle the dish of a radio telescope operates in the same manner as the?
Concave mirror of a reflecting telescope
Why are observatories located on remote areas?
Observatories are built at high altitudes to minimize the distance incoming light has to travel through the atmosphere, which distorts the images. Also, remote locations have much less light pollution and other air pollution than populated areas.
Why do people use telescopes to project the image of the solar eclipse on a cardboard?
you have just been trolled
Why does a telescope work at night?
Telescopes do not normally work well at night, unless you happen to be looking at stars and other planets. This is because the stars do not depend on our Sun shining on them to be bright.
Think of the stars as you would, say, a row of flashlights a block away. With the naked eye with no moon or streetlights, you may not be able to see much farther than 15 or 20 feet, yet those flashlights at the other end of the block are very easy to see. The stars are similar: they make their own light, and you can see them a looong way away.
