What is radic telescope?

A radio telescope is a form of directional radio antenna used in radio astronomy. The same types of antennas are also used in tracking and collecting data from satellites and space probes. In their astronomical role they differ from optical telescopes in that they operate in the radio frequency portion of the electromagnetic spectrum where they can detect and collect data on radio sources. Radio telescopes are typically large parabolic ("dish") antennas used singly or in an array. Radio observatories are preferentially located far from major centers of population to avoid electromagnetic interference (EMI) from radio, TV, radar, and other EMI emitting devices. This is similar to the locating of optical telescopes to avoid light pollution, with the difference being that radio observatories are often placed in valleys to further shield them from EMI as opposed to clear air mountain tops for optical observatories.


How radio telescopes differ from optical telescopes.?

Radio telescopes collect radio waves. Optical telescopes capture visible light waves.


Are optical telescopes much bigger then radio telescopes?

No they are not bigger then radio telescopes at all.


How do radio telescopes gathering data?

Radio telescopes gather data from radio sources and they target the radio frequency part of the electromagnetic spectrum.


What kind of telescopes do radio telescopes use?

Radio telescopes are basically specially designed antennas. They don't "see" anything. They "hear".


What are radio static letters?
