WebSpectroscopy is a fundamental tool that astronomers use to study the Universe. Spectrographs are instruments that are used to conduct spectroscopy. They provide scientists with the data they need to analyse the materials that make up stars, nebulae, galaxies and the atmospheres of planets. WebOn a smaller scale, astronomers use spectroscopy to measure the the motion of a star in a binary star system, from an orbiting exoplanet, due to the tug of a black hole, or any number of other possibilities. The motion of the star toward us blueshifts the light slightly, moving it to shorter wavelengths, while moving away redshifts the light.
