Brainliestradio telescopes video—text versioncelestial bodies emit different types of radiation, only some of which can be detected by traditional telescopes. radio waves are invisible rays that can be detected only by radio telescopes. a radio telescope functions like a television antenna. radio waves from space are sensed by a gigantic parabolic reflector, which concentrates them toward the top of a focusing antenna. a radio receptor converts the radio waves into electrical signals which are amplified and then transmitted to the center of the parabola. they are then recorded and analyzed in the laboratory so that scientists can obtain a radio image of the source observed. the parabolic antenna can usually be oriented to detect radio waves from all directions of space. some radio telescopes are fixed. the largest radio telescope in the world, located in arecibo, puerto rico, is fixed. built in a natural valley shaped like a giant parabola, its reflector measures 305 meters in diameter. mobile detectors suspended from cables permit the scanning of one of part of the sky. unlike traditional telescopes, radio telescopes can be used both day and night, even when there is cloud cover. questions describe how radio telescopes are used to explore space. how are radio waves used on earth? why do radio telescopes convert radio waves (analog signals) to electrical (digital) signals for analysis? (hint: what did the article say about the advantages of digital signals? )
