What are three primary contributions to Astronomy?
Galileo's desktop telescope, Edwin Hubble's Galaxy Tracker, and Radio Telescopes -as in The Very Large Telescopic Array - the VLTA.
What and where are the largest optical telescopes in use today?
Ccd's and in large telescopes
Are telescopes dangerous?
Telescopes are not dangerous in normal operation. A large telescope might hurt you if it fell on you.
Why are large telescopes used to study distant galaxies and not small telescopes?
my guess is that larger telescopes are stronger than smaller ones. which means they can see farther. .
Connecting multiple telescopes together to combine the images is called?
telescopes

What telescopes is the largest reflecting refracting x-ray or the very large array?
It's difficult to understand the question, but WikiAnswers doesn't do well with multiple choice questions. In general, refracting telescopes are smaller than reflecting telescopes; a refractor has the light going straight through the tube, and structural considerations force limits on its size. In a reflecting telescope, the light path is folded back on itself, and reflecting mirrors reflect more light than thick lenses can pass through. But the largest current reflecting telescope is perhaps 300 inches in diameter, although larger ones are planned. By contrast, the Very Large Array of radio telescopes is ACRES in total size, and there is no theoretical limit in how large "it" could be - because "it" is actually "they". Dozens, potentially hundreds of radio telescopes can add their size together to develop a more sensitive and more precise instrument.
Reflecting telescopes differ from refracting telescopes in having what?
Two large objective lenses.
How is the VLA similar to an optical telescope?
well,both telescopes let you look into the ground into the inner core and you see deep in he atmosphere which is space. Errr... The Very Large Array is an array of radio-telescopes, i.e. it detects radio emissions from stars and similar. An optical telescope as its name suggests, collects visible light. The similarity is that increasing the aperture increases the radiation-gathering power by a square-law. In an optical telescope this is achieved by a larger mirror (or lens but most large telescopes are reflecting.) The VLA uses a "synthetic aperture" to gain the advantages of increasing its gathering area without the cost and complexity of building a single, very large dish.
Why big telescopes?
Large telescopes have improved resolution over small telescopes and as such can gather clearer images of objects further away.

Why are large telescopes made?
to see uranus

What type of radiation does the VLA telescope give off?
None whatsoever. The Very Large Array COLLECTS radiation, in the form of radio waves. The array has to be Very Large, because the signals are so incredibly faint. In fact, the energy of a single match, the kind you might use to light a campfire, is more than the energy collected in all the radio telescopes in the world in the last 100 years!
Large telescopes are often housed where?
On top of mountains.
