Electromagnetic radiation carries most of the information astronomers receive from the universe. Multiwavelength astronomy combines observatories on the ground and in space because Earth's atmosphere transmits some bands well and blocks others.

Light can be described both as an electromagnetic wave and as quantized packets of energy called photons. Photon energy explains why ultraviolet and X-ray radiation can ionize matter more readily than radio waves and why detector technology changes across the spectrum.

A blackbody is an idealized object that absorbs incident radiation perfectly and emits a continuous spectrum determined only by its temperature. Astronomers estimate stellar temperatures from color and continuum shape, infer luminosities when size is known, and model thermal emission from planets, dust, and cosmic backgrounds.

Spectral lines are narrow wavelength features produced when atoms, ions, or molecules exchange energy in quantized transitions. Spectroscopy lets astronomers determine what distant objects are made of without sampling them physically and provides some of the most precise measurements of radial velocity.

The Doppler effect changes the observed wavelength of radiation when a source and observer have relative motion along the line of sight. Doppler measurements reveal radial velocity but not the full three-dimensional velocity by themselves.
