An instrument used to collect, measure, or analyze electromagnetic or other radiation from distant objects. A telescope overcomes the limitations of the human vision by increasing the ability to see faint objects and discern fine details. In addition, when used in conjunction with modern detectors, a telescope can “see” light that is otherwise invisible to the human eye (Fig. 1). The wavelength of the light of interest can have a profound effect on the design of a telescope. By analogy, detectors of particles from space are also known as telescopes.
