Amateur astronomers have built their own radio telescopes in their back yards for a couple of hundred dollars in spare electronic junk parts. It is especially inexpensive if you happen to have access to an old 6-foot satellite TV "dish" antenna. If you have a little electronics experience - as a "HAM" radio operator, for example - it's easy to do.
Of course, bigger dishes are more expensive.....
One of the ways around the problem of big, heavy, expensive dish antennas is to create an array of smaller dishes that are all aligned together. This is the concept behind the Very Large Array of radio telescopes. And when your sponsor is Paul Allen, business partner of Bill Gates, things like the Allen Radio Telescope is pocket change in comparison.

∙ 13y agoA gamma telescope is like any other telescope except unlike the traditional telescope that detects visible light, it detects gamma rays, high energy electromagnetic waves with much shorter wavelenghts which are invisible to the human eye.
Gamma rays because of their high energy nature are rare and created in high energy astrophysics such as supernova. Swift combines a gamma ray telescope with an X-ray telescope and UV telescopes to detect high energy events and their afterglow.

∙ 12y agoYes, I suppose you could, from ebay.co.uk or from alibaba.com with price of 20,000 USD or more. the system is included 4.5 meter motorized dish, receiver system etc. this kind of system is useful for observation of strong Celestial sources like CAS-A, Sun, moon and more than 100's of radio sources. you also able to make a map of sky and many more... The manufacturer of this system is Swedish Company with name of POAM Electronics Ltd.

∙ 14y agoThe function of a "telescope" is to focus and manipulate the electromagnetic radiation to give a magnified and amplified view. Radio, microwaves, heat, light, UV, X-rays and gamma rays are all electromagnetic radiation; just shorter wavelengths and higher frequencies as you go up the spectrum.
With light telescopes, we use mirrors and lenses; with radio telescopes, we use enormous "dish" antennas which act as mirrors in the radio spectrum.
With gamma rays, we do not yet have any way to magnify or manipulate them; so there are not (yet!) any gamma ray telescopes.

Would it make sense to place an X-ray or gamma ray telescope on a mountain top?
No, x-rays and gamma rays are blocked by our atmosphere, if you want to observe them, you have to go into space.
What is a good place to put a telescope?
optical telescopes - high mountain far from city light pollutionradio telescope - anyplace with little radio interference in the bands it operates inx-ray or gamma ray telescope - in orbitneutrino telescope - deep in an abandoned salt mine.etc.
Why does it take the same time for gamma waves and light waves to travel from a star to space telescope?
Because electromagnetic radiation at all wavelengths travels through vacuum at the same speed.
When was a telescope first used in space?
If you would consider a non visible light telecope, then the first such telescope was the gamma ray observatory OAO-1, which was set into orbit by NASA. For visible light it is was with the launch of Hubble by NASA in 1990.
Do x ray and gamma ray telescopes have the same design as an optical instrument?
No, x-rays and gamma rays cannot be focused by lenses or conventional telescope mirrors. To make mirrors that will focus x-rays or gamma rays you need very shallow glancing angle mirrors, that are nearly just parabolically tapered tubes. Typically several of these tubes with the same focal point but different diameter are nested inside each other.
What are types of space telescope?
Gamma, X-ray, Optical, and Radio
Would it make sense to place an x-ray or gamma ray telescope on a telescope?
No because, most ultraviolet radiation are blocked by earth's atmosphere.
What are NASA's the best observatories?
There are four: Hubble Space Telescope, Compton Gamma Ray Observatory, Chandra X-ray Observatory, and the Spitzer Space Telescope.
What satellite observatories is used to examine the collision of neutron stars?
Femi Gamma Ray Telescope
How are galaxies investigated?
galaxies are investigated in certain ways such as..... 1. Telescope. 2. Radio telescope. 3. Infra red telescope. 4. Gamma telescope. 5. Pure physics. 6. Mars and Lunar landers. 7. Fly-by missions
What are the advantage of using a telescope?
The main disadvantage of a gamma telescope is that the rays penetrate everything making it difficult to reflect them. The advantage is that they can view wavelengths outside of the Earth's atmosphere.
Would it make sense to place an X-ray or gamma ray telescope on a mountain top?
No, x-rays and gamma rays are blocked by our atmosphere, if you want to observe them, you have to go into space.
Where should a telescope designed to detect gamma radiation be positioned on a hill?
at the top :) cause it can see more stars (;
Where is the Fermi gamma ray telescope located?
In low earth orbit, perigee 333 miles, apogee 344 miles, inclination 25.58 degrees, orbital period 95.40 minutes, velocity 17,000 miles per hour. Gamma ray (and x-ray) telescopes must be in space because the atmosphere is opaque to gamma rays (and x-rays).
What is a good place to put a telescope?
optical telescopes - high mountain far from city light pollutionradio telescope - anyplace with little radio interference in the bands it operates inx-ray or gamma ray telescope - in orbitneutrino telescope - deep in an abandoned salt mine.etc.
Does the andromerta constellation have any binary stars?
Gamma Andromedae, "Almach" is a spectacular quadruple star in Andromeda. Two of the stars can be seen with a small telescope, colored red and blue.
Why does it take the same time for gamma waves and light waves to travel from a star to space telescope?
Because electromagnetic radiation at all wavelengths travels through vacuum at the same speed.
