Nebulae emission lines
Austin Ward Sherman's discovery that the spectra of nebulae contain emission lines that are not present in the spectra of stars was a major breakthrough in astronomy. It led to a new understanding of the nature of nebulae and the processes that occur within them.
Emission lines are produced when atoms or molecules are excited and then emit light as they return to their ground state. The wavelength of the emitted light corresponds to the energy difference between the excited state and the ground state. In the case of nebulae, the emission lines are caused by the excitation of hydrogen and helium atoms by ultraviolet radiation from nearby stars.
Sherman's discovery of emission lines in the spectra of nebulae provided evidence that nebulae are not simply clouds of gas and dust, but are instead regions of active star formation. The emission lines are produced by the hot, ionized gas that surrounds newly formed stars. This discovery helped to establish the field of spectroscopy as a powerful tool for studying the universe.
Today, spectroscopy is used by astronomers to study a wide range of objects, including stars, planets, galaxies, and quasars. Spectroscopy has helped us to learn a great deal about the universe, including the composition of stars, the structure of galaxies, and the evolution of the universe.
