Telescopes and the Electromagnetic Spectrum

We use special tools to detect things far away that we can't see with just our eyes. Many tools use different wavelengths on the electromagnetic spectrum (EMS) including visible light, infrared light, ultraviolet light, and radio waves. Other tools may detect magnetism—such as the magnetic field lines around the surface of the Sun.
