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 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 are three primary contributions to Astronomy?
Observing and studying celestial objects and phenomena, such as stars, planets, and galaxies. Developing theories and models to explain the behavior and structure of the universe. Using technology, such as telescopes and satellites, to gather data and expand our understanding of space.
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.
The primary reason for spreading many radio telescopes across a large area and combining the signals at a central station is?
to increase the resolution of the telescope system. By having multiple telescopes spread out, the system can simulate a larger telescope, which allows for more detailed observations of celestial objects. Additionally, this setup improves the sensitivity of the telescope array, enabling it to detect fainter signals.

What kind of telescope do you need to most easily see a neutron star?
To most easily observe a neutron star, a powerful telescope with capabilities for high-energy astrophysics is required, such as a radio telescope or an X-ray observatory. Neutron stars emit primarily in the X-ray and radio wavelengths, so instruments like the Chandra X-ray Observatory or the Very Large Array (VLA) for radio astronomy would be ideal. Optical telescopes are generally not effective for observing neutron stars directly due to their faintness in visible light.
What is the largest land telescope in the world?
The Atacama Large Millimeter/submillimeter Array (ALMA) located in Chile is the largest land-based telescope in the world. It consists of 66 radio telescopes and is used to study wavelengths in the millimeter and submillimeter range.
Connecting multiple telescopes together to combine the images is called?
telescopes
