  • A. Near Infrared Imager and Slitless Spectrograph
    The Near Infrared Imager and Slitless Spectrograph (NIRISS) is a James Webb Space Telescope instrument designed for high-sensitivity near-infrared imaging and spectroscopy, particularly suited for exoplanet characterization and studies of distant galaxies.
  • B. Space Telescope Imaging Spectrograph
    The Space Telescope Imaging Spectrograph is a versatile instrument on the Hubble Space Telescope that performs high-resolution imaging and spectroscopy across ultraviolet, visible, and near-infrared wavelengths to study the physical properties of astronomical objects.
  • C. Imaging IR Spectrometer
    The Imaging IR Spectrometer is a Chandrayaan-2 orbiter instrument designed to map the Moon’s surface composition by measuring reflected and emitted infrared radiation.
  • D. Boller and Chivens spectrograph
    The Boller and Chivens spectrograph is an astronomical instrument designed for dispersing and analyzing light from celestial objects to study their physical and chemical properties.
  • E. Near Infrared Camera and Multi-Object Spectrometer
    The Near Infrared Camera and Multi-Object Spectrometer (NICMOS) is a Hubble Space Telescope instrument designed to capture high-resolution images and spectra in the near-infrared, enabling studies of faint, distant, and dust-obscured astronomical objects.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
