What is the advantage of placing two small radio telescopes 100 meters apart?
Placing two small radio telescopes 100 meters apart allows for interferometry, which enhances the overall resolution of the observations. This configuration effectively simulates a larger telescope with a diameter equal to the distance between the two dishes, enabling the detection of finer details in astronomical objects. Additionally, combining data from both telescopes improves sensitivity and signal quality, allowing for more accurate measurements of celestial phenomena.
Why do you use only two types of telescopes here on earth optical or radio telescopes?
Radiation other than light and radio waves hardly penetrates Earth's atmosphere.
How far can you see with a radio telescope?
Radio telescopes can detect radio waves from celestial objects billions of light-years away, allowing scientists to observe phenomena such as quasars, pulsars, and the cosmic microwave background radiation. The distance at which a radio telescope can "see" depends on the strength of the signal emitted by the object being observed and the sensitivity of the telescope's receivers.
When multiple radio telescopes are used for interferometry resolving power is most improved by increasing?
Increasing the distance between the two most widely separated radio telescopes has an enormous effect on resolution.
Why do single dish radio telescopes have poor resolving power compared to optical telescopes of the same diameter?
Radio telescopes are generally much larger than optical telescopes for two reasons: First, the amount of radio radiation reaching Earth from space is tiny compared with optical wavelengths, so a large collecting area is essential. Second, the long wavelengths of radio waves mean that diffraction severely limits the resolution unless large instruments are used.
What is Data from multiple radio telescope is combined with?
Two or more radio telescopes!
What are the two ways scientists explore space?
light telescopes and radio telescopes whether installed on earth or on space vehicles

Distance between two radio telescopes?
The distance between two radio telescopes is important for interferometry, a technique used to combine signals from multiple telescopes to improve resolution and sensitivity. By measuring the time delay between the signals received at each telescope, scientists can determine the distance between them and use this information to create detailed images of celestial objects.
Why are radio telescopes typically built so large compared with optical telescopes?
Radio telescopes are much larger than optical telescopes because of wavelength. Earth's atmosphere has two major "windows" where it is transparent to photons: 300 nm - 800 nm: optical wavelength window (approximate) 30 mm - 30 m: radio wavelength window (approximate) Even the shortest-wavelengths used by radio telescopes at around 30 mm are still thousands of times longer than the longest wavelengths used by optical telescopes. The wavelength has 2 effects on the size of a telescope: * The angular resolution (in order to distinguish 2 nearby stars, FWHM) depends on the wavelength/aperture ratio. Radio-frequency photons require a wider aperture to focus than visible-light-frequency photons, so radio telescopes *must* be larger to get a reasonable resolution. * A telescope typically requires the collecting area to be aligned within 1/10 of the wavelength it is designed for. Because it is almost impossible to get all the parts of a sufficiently large telescope aligned to within 80 nm, radio telescopes *can* be built much larger.
How is a radio telescope different from both a refracting and a reflecting telescope?
Well, its simple, there are two things that are in common.... both telescopes have a eye peice and a radio telescope doesnt.... theres more to it and the radio telescope looks way diffrent then the regular ones..... Wow! What a non-answer this person has given! For one thing, radio telescopes look more like satellite dishes than traditional telescopes. Rather than operating on the visible light spectrum as a reflecting or refracting telescope would, radio telescopes gather information from the infrared light spectrum - radiation waves. These radiation waves are collected to form a picture of whatever the radio telescope is looking at. I'm not a scientist; I'm not an astronomy student. I just did a little bit of research that the original answerer obviously didn't do.

Why do astronomers continue to build even larger telescopes?
Radio telescopes allow us to see things that can't be seen in visible light. And vice versa, optical telescopes can show things that are not visible in radio telescopes. So, the information from both kinds of telescopes really complements each other.
