What is the base line of a radio telescope array?
The distance between the two antennae that are the farthest apart is the baseline of a radio telescope array..
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.
Group of radio telescopes?
Currently, the radio telescope at Aricebo in Puerto Rica at 305 m diameter is the largest.In hand are plans for a SKA telescope (see skatelescope.org) in the southern hemisphere. This enables our Milky Way galaxy to be studied. The total area of the many dishes will be 1 sq km, hence the name. The resolution of a radio telescope is determined by the length of the baseline, and in this case, South Africa, Australia and New Zealand are collaborators for the ground stations. There are intended to be several different types of aerials to cover a few hundred megahertz, out to a few thousand megahertz. Construction is expected to start in the near future.
Disadvantages of infrared telescope?
The main disadvantage of a radio telescope is the poor resolution of the images they obtain. This isn't due to a flaw in the design, but in a limitation of the radio signals they observe. The longer the wavelength of light (radio waves are light!) the fuzzier the image you receive. In order to combat this, a larger telescope is needed. Radio telescopes are thus the largest astronomical telescopes, measuring hundreds of meters across (e.g. Arecibo radio telescope) or composed of many smaller dishes in large arrays of dozens of radio dishes (e.g. VLBA, Very Long Baseline Array). Another disadvantage is the amount of human generated noise can easily interfere with the telescopes, and is harder to isolate and shield than from light pollution, as it easily reaches beyond horizons and around terrain and obstacles. This can require remote observation sites. They also have many advantages, but that isn't the purpose of this question.
Why is there so many hair types?
Hair styles are an expression of an individual person, a group, or a culture. And because the human race is a so broad in its views on estheticism, the array of hairstyles reflects this diversity.
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 is it called when scientists use more than one telescope to look at the same object?
Interferometry. First used in radio telescopes optical instruments were a "relatively" recent addition to the process. It is the interference of signals that is used to create resolution. The further the instruments are apart the better it works.
What is the 4 c?
The 4C array is a type of radio telescope that is a cylindrical paraboloid. One can find this telescope at the Mullard Radio Astronomy Observatory in Cambridge, England.
What electromagnetic radiation does the Australian Telescope detect?
The Australia Telescope Compact Array (ATCA) is a radio telescope.If the telescopes are operating in "aperture synthesis mode" they will produce radio images.
When was Pachmarhi Telescope Array created?
Pachmarhi Telescope Array was created in 1986.
What is the 1 mile telescope?
The One-Mile Telescope [See Link] at the Mullard Radio Astronomy Observatory was completed in 1964. It is an array of radio telescopes (2 fixed and 1 moveable, fully steerable ) designed to perform aperture synthesis interferometry. The telescope was used to produce the 5C catalogue of radio sources. Observations with larger incremental spacings were used to observe individual radio sources with unprecedented sensitivity, angular resolution, and image quality.

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.
What type of telescope is the famous telescope that orbits the earth?
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.
What is VLA in astronomy?
VLA in astronomy is the Very Large Array (better known as the Karl G. Jansky Very Large Array. It is a radio astronomy observatory located on the Plains of San Agustin, New Mexico, USA.See related link for more information.
