radar telescopes

Radar telescopes use radio waves to detect and study objects in space, similar to how regular radar finds airplanes. Instead of visible light, they emit radio signals that bounce off celestial bodies like planets, asteroids, or space debris. By analyzing the returning signals, radar telescopes can determine an object’s distance, speed, size, and surface features. This technique allows scientists to map space objects more precisely, especially those too faint or distant for visible light telescopes. Radar telescopes are valuable for tracking near-Earth objects and exploring planets and moons in our solar system.
