Explanation:

Telescopes, especially astronomical telescopes, detect radiation (like visible light, radio waves, X - rays, etc.) emitted or reflected by celestial objects. Magnetism, motion, and speed are not directly detected by telescopes in the way that helps in discovering new astronomical objects as the primary detection method. Radiation from stars, galaxies, and other celestial bodies is what telescopes capture to study and discover new objects in space.
