Radio telescopes are specialized instruments used to detect and study radio waves emitted by celestial objects in space. They are designed to collect radio-frequency radiation from objects such as stars, galaxies, and other astronomical bodies. Radio telescopes can provide valuable information about the composition, temperature, density, and motion of these objects, helping scientists to better understand the universe and its many mysteries. These telescopes are typically large, dish-shaped structures that can be found in observatories around the world.
