Radio Astronomy

Most radio telescopes are concave dish shaped to collect radio waves emitted by stellar bodies.

We know that all astronomical objects do not liberate visible light. But some of them emit radio waves. Radio telescopes are used to collect such radio waves. Radio telescopes can obtain additional information about familiar objects, as well as seek out new ones. They sometime can also locate too dim or distant objects which cannot be observed by Space telescopes.

The radio telescope at France is 200 meters long and 35 meters in height. It can pick up signals from stars that pass directly in front of the Earth.
