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.

What instruments use lenses or mirrors to collect and focus light from distant objects?
A Telescope uses lenses or mirrors to collect and focus light from distant objects. With the advancement in optical research we are capable to watch the stars and planets better than before. Our information about universe largely depend on telescopes.
The Newtonian reflector has a convex primary mirror and a flat secondary mirror with the eyepiece located on the top side of the telescope tube.
What is something you might look through a telescope to see?
More than you can see from earth.
The earth's atmosphere (and light-pollution) diminish what one can see with a telescope on the surface of the earth. From space the telescope can see much further in both space and time - the light from something we can see in space left that object many years ago. The light from the sun takes about eight or nine minutes to get to earth. The light from the nearest star takes about four years to get here. The farther back you can see across space, the farther back in time you are looking.
If you are a child, then i would recommend the national geographic 50mm telescope. you can get these from argos. They are very good, for you can view the moons craters, jupiters moons, saturns rings, mercury, and much more, they can also be used to see things in the same room as you, but can still show very high quality images
How do telescopes and the electromagnetic spectrum work together to help us explore space?
Telescopes are used to observe and magnify images in outer space. The electromagnetic spectrum consists of many wavelengths, which constitute visible light, infrared, microwave, and X-ray radiation. Telescopes can be manufactured to view these certain types of radiation.
Where is the Spitzer space telescope located?
The Spitzer space telescope belongs to NASA. The Spitzer space telescope was launched into space in August 2003 . It captures images of the planets and other objects in the universe that cannot be observed from earth.
What was the first telescope built by the NASA?
The first telescope was not built by NASA. It was built by Galileo.
However, no one gives a f**k. It could've been built by anyone but was never recorded. If your teacher asks, just give him/her your middle finger and say no.
What is the difference between a reflecting telescope a refracting telescope and a radio telescope?
Reflecting telescopes are usually designed to capture and concentrate light through the use of a large concave mirror which focuses the captured light on a smaller, flat mirror which in turn reflects it to the eye or a camera.
Refracting telescopes use convex lenses to capture light and focus it where the eye or a camera is.
Radio telescopes collect long wavelength radiation (radio waves and microwaves) and are all forms of reflecting telescope.
The first telescopes were refracting telescopes, because the technology existed to form the needed sizes of convex lenses. Reflecting telescopes were developed later, when advancing technology provided the means of making very regular concave mirrors. All the largest modern telescopes are variations on the reflecting telescope design because it is easier to make and manage very large concave mirrors than it is to make lenses of equivalent light collecting power.
Why are radio telescopes considered to be dependable telescopes?
So that the telescope's camera is high quality and can zoom enough for a large, HD picture. Also, the quality of the connection has to be powerful so the picture doesn't decrease (lose) quality when it reaches the place it is being sent to (e.g. Lab) via radio.
What is the most important part on the Hubble Space Telescope?
There are 2 key pieces of electronics aboard HST that if they were to fail would essentially end HST's service life:
Fine Guidance Sensors (FGS) are arguably the single most key pieces of electronics on HST. The FGS's are what point HST and keep it locked in position while observations are being made, a difficult task considering that HST orbits the Earth every 96 minutes, and is subject to extreme thermal stresses every time it passes through the solar terminator (the line between darkness and sunlight in orbit).
Science Instrument / Command & Data Handling Unit (SI C&DH) - The very first item I worked on during my years with the HST program, the SI C&DH converts all science data from HST observations prior to relaying to the ground via telemetry. Without this key unit, data from Hubble could not be transmitted to the Space Telescope Science Institute in Maryland (HST's control center), and HST's function would be useless. There are 2 SI C&DH units, one primary and one backup. One failed just prior to the last servicing mission; it was delayed so a spare unit (there are always at least 1 or 2 flight units available on the ground, or if necessary an engineering unit can be made flight-ready) could be readied and the Astronauts could prepare for replacing this key unit.
A binocle is a dioptric telescope fitted with two tubes joining, to enable to viewing of an object with both eyes at once.
Do telescopes use a reflecting mirror to focus light onto a small area?
Many telescopes do, especially the largest ones.
Others use a refracting lens to do that job.
(Note: Our entire discussion so far has included a redundant amount
of redundancy. All mirrors reflect, and alllenses refract.)
Does the Hubble Telescope belong to NASA?
Yes, the Hubble Space Telescope is a project of NASA (National Aeronautics and Space Administration), in partnership with the European Space Agency (ESA). It was launched by NASA in 1990 and has provided valuable insights into the universe through its observations.
What filter should I use on my telescope for observing a galaxy?
None. Unless you are taking photographs, filters just hinder the view of a galaxy. The best way to get good views is with a sky with no light pollution.
Edwin Hubble was a American astronomer, the Hubble telescope is named after him.
Could someone without a telescope see Saturn?
Yes, Saturn is readily visible to the naked eye. But you can't see the rings and moons without a telescope.
How do you look through the telescope on moshi monsters?
To look through the telescope in Moshi Monsters, click on the telescope icon on the map. This will open up the telescope view, where you can use the arrow keys to move the telescope and discover different parts of Monstro City.
Does an optical telescope and a radio telescope of the same size have the same angular resolution?
No, they do not. The angular resolution of a telescope is determined by the wavelength of the radiation it is measuring and its diameter. Since optical telescopes detect shorter wavelengths than radio telescopes, they generally have better angular resolution for viewing fine details.
Can you Makemake without a telescope on Earth?
No. It is too small and too far away to be seen with the naked eye, despite its relative brightness when observed by telescopes.
The surface of a radio telescope doesn't have to be as flawless as the surface of an optical telescope because the radio telescope is collecting radio waves, something that will not be affected by faults in the glass. Optical telescopes, on the other hand, are collecting light, where faults in the surface can interfere with the image.
How is Refraction used in lenses for eye glasses contact lenses cameras and telescopes?
it magnifys it like alott
What are the disadvantages of the Jodrell Bank telescope?
The Lovell Telescope is a large radio-astronomy telescope located in England. As a radio telescope, it doesn't capture light waves to make pretty pictures; it captures radio waves in order to determine what other sorts of things might exist in space.
As a radio telescope, it really does its job well and has no major disadvantages. Unless you like pretty pictures; for that you'll need to go to hubblesite.com.
