Space Telescope Imaging Spectrograph

The Space Telescope Imaging Spectrograph (STIS) is an instrument aboard the Hubble Space Telescope designed to observe light from celestial objects in great detail. It combines imaging and spectroscopy, which means it captures pictures and also breaks down light into its component colors. This allows scientists to analyze the composition, temperature, density, and movements of stars, galaxies, and other cosmic phenomena. STIS helps us understand the universe's structure, origins, and the processes that govern astronomical objects, making it a vital tool in modern astrophysics.
