The Webb telescope's Near Infrared Spectrograph (NIRSpec) instrument will be used to study star formation and the chemical composition of young, distant galaxies. The instrument breaks near-infrared light into its components for closer examination and analysis. But what makes NIRSpec even more special is its "multi-object" capability which enables it to look at as many as 100 objects at the same time.
