This site from NASA\'s Infrared Astrophysics Data Center explains how the universe can be observed using the entire electromagnetic spectrum. There is an introduction to using light in astronomy; information on and images taken from different areas of the electromagnetic spectrum of objects in the solar system, the Milky Way galaxy and beyond; and a table of radiation types, their characteristic temperatures, and objects emitting this type of radiation. The tutorial explains how observations are made using X-rays, gamma rays, ultraviolet light, visible light, infrared wavelengths, and radio wavelengths. There is a section on why telescopes are sent to space and a multiwavelength gallery.
