For astronomers, spectrographs mounted on the largest telescopes are a primary tool to carry out their work. This is particularly true for stellar archaeology studies. This way the data needed for a chemical abundance analysis -- stellar spectra -- can be obtained. Some of the best telescopes in the world are the twin Magellan telescopes, which each have a mirror that is 6.5 m in diameter. They are located in Chile in the Southern Hemisphere where the night sky is particularly bright and beautiful to watch, for astronomers and lay people alike! Get a peek into what it means when astronomers go observing.
