What type of telescope is the famous telescope that orbits the earth?

Answer 1

There are a few frequency bands of electromagnetic radiation that are absorbed by our atmosphere; if we want to observe the cosmos in those bands, we need to place our telescope in space above the atmosphere. The most "useful" of these is the infrared band, with frequencies a little below those of visible light.

Answer 2

Telescopes can be broadly classified into two types:

• Optical Telescopes
• Non-Optical Telescopes

Optical Telescopes

Optical telescopes are those telescopes that are to used to observe electromagnetic radiation in the visible region of the electromagnetic spectrum. Most often, while using these telescopes, we see the image directly with our eyes. Some optical telescopes like the VLT (Very Large Telescope) or the Hubble Space Telescope take digital pictures of the images and store it.

Optical telescopes are of two principle types:

• Refractors
• Reflectors

Refractors

This is the first kind of telescope invented by a dutch optician Hans Lippershey and perfected by Galileo Galilei. It uses two convex lenses to refract light and form an image of the object.

Refractors can be used for terrestrial as well as astronomical purposes

Reflectors

This kind of telescope was invented by Isaac newton. It uses two parabolic mirrors to focus light into the eyepiece, and hence form an image of the object. It is generally used for astronomical observations only.

Other kinds of telescopes which use a combination of mirrors and lenses also exist.

Non-optical telescopes

These telescopes are used to observe electromagnetic radiation in the non-visible region region of the EM spectrum. These include

• Radio
• Microwave
• Infrared
• Ultraviolet
• X-ray
• Gamma Ray

We do not observe the images from these telescopes directly. The telescopes capture images and the data is formatted so that we can view it. For example, an infrared telescope would gather IR light, but we cannot view IR light with our eyes. So it converts each of the respective IR wavelengths into colors we can see.

Space Telescopes

Both, optical and non-optical telescopes are launched into space to get better astronomical readings. In space, there is no atmospheric disturbance, and we can obtain images throughout the day.

Some space telescopes are:

• Hubble Space Telescope - Optical telescope
• Spitzer Space Telescope - Infrared telescope
• Chandra X-ray Observatory - X-ray telescope
• SWIFT - Gamma Ray telescope
• WMAP - Microwave telescope

Answer 3

Telescopes that work with light and radio waves can work from Earth´s surface. Any other types of electromagnetic waves will hardly reach Earth's surface, so to use those (e.g., X-rays, infrared, and others), telescopes have to be taken to outer space.

Answer 4

A good example would be an infrared telescope.

They can actually be used at high altitudes on Earth to escape a lot of the atmospheric absorption of infrared radiation.

Answer 5

They use telescopes, sattelites, and spaceships.

Answer 6

these are TV TELESCOPE,RADIO TELESCOPE,REFRACTING TELESCOPE,REFLECTING TELESCOPE

Answer 7

The Hubble Space Telescope is a Ritchey-Chretien type of reflector design.

Answer 8

The Hubble telescope is in orbit around the Earth.

Answer 9

A radio telescope.

Answer 10

x ray telescopes
