A radio telescope is a radio receiv

A radio telescope is a radio receiver that "sees" radio waves. Unlike a normal telescope, which sees light, a
radio telescope is used primarily in the area of astronomy because it can detect radio waves that are emitted by
celestial objects. Such objects in space, also called radio objects, can be things such as hot gas, electrons, and
wavelengths given off by different atoms and molecules.
The first radio telescope was invented by Grote Reber in 1937. He was an American who graduated with a degree in engineering. He went on to work as an amateur radio operator and later decided to try to build his
own radio telescope in his backyard. Reber's first two radio receivers failed to pick up any signals from outer
space, but in 1938, his third radio telescope successfully picked up radio waves from space.
A radio telescope consists of a large parabolic-shaped dish antenna or a combination of two or more. The significance of the parabolic shape allows for the incoming radio waves to beconcentrated on one focal point,
allowing the signals to be picked up as strongly as possible. A larger dish means that more signals can be received and focalized.
