Although optical telescopes are the type most commonly used for stargazing and amateur astronomy, lots of astronomical research is done on telescopes that look at other wavelengths of light. Each of these wavelength ranges shows us something unique about the universe and allows us to view events and objects that can't be seen with human eyes.
The radio telescope is used to detect most of the things that an optical telescope can not see. The comments of a radio telescope are the same as in a car radio. The both have the antenna, the receiver, the detector, and the computer or speaker. The radio telescope's dish has to be very large. The reason for this is that the radio telescope detects very weak signals. So it has to be big to do that. The dish of a radio telescope collects all the waves at the wave length that the receiver is tuned to.
