The instruments allow astronomers to unlock the secrets of the universe by dissecting light into spectra and providing detailed chemical analyses of celestial objects and their origins. The Giant Magellan Telescope can accommodate up to ten instruments, more than any other telescope. Each one has a unique ability to explore the unknown: from analyzing a distant planet’s atmosphere in search of life to looking back in time to when the universe first formed. The discoveries they make could rewrite history as we know it.
