Description	English: Illustrates cumulative absorption spectra observed by Hubble. A beam of light coming to Earth from a distant quasar passes through numerous intervening gas clouds in galaxies and in intergalactic space. These clouds of primeval hydrogen subtract specific colors from the beam. The resulting "absorption spectrum," recorded by Hubbles Space Telescope Imaging Spectrograph (STIS) is used to determine the distances and chemical composition of the invisible clouds. Français : Illustration des spectres d'absorption observés par le télescope spatial Hubble. Un faisceau lumineux provenant d'un lointain quasar passe à travers plusieurs nuages gazeux lors de son voyage dans l'espace. Ces nuages d'hydrogène primitif retirent certaines raies spectrales du faisceau. Le spectre d'absorption résultant, enregistré par le Space Telescope Imaging Spectrograph (STIS) de Hubble est utilisé pour déterminer la distance et la composition des nuages invisibles.
