Multiwavelength Astronomy

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.
