The Emission Spectrum

The emission spectrum, produced by all hot and transparent gases. It consists of straight bright lines on a black background, with the bright lines being characteristic of the chemical elements in the gas. Emission spectra are produced by gases in everything from a gas burner to a nebula (a nebula can be thought of as a fairly hot cloud of gas and dust).
