  • A. Ultraviolet Spectrometer
    The Ultraviolet Spectrometer was a scientific instrument on the Galileo spacecraft used to analyze ultraviolet light from celestial objects to study their composition, atmospheres, and energy processes.
  • B. Ultraviolet Imaging Spectrograph (UVS)
    The Ultraviolet Imaging Spectrograph (UVS) is a scientific instrument that observes ultraviolet light to study the composition, structure, and dynamics of Jupiter’s atmosphere and auroras.
  • C. Far Ultraviolet Camera/Spectrograph
    The Far Ultraviolet Camera/Spectrograph was a pioneering lunar-based telescope that captured ultraviolet images and spectra of stars, Earth, and the interplanetary medium from the Moon’s surface.
  • D. Ultraviolet/Optical Telescope
    The Ultraviolet/Optical Telescope is a space-based instrument designed to capture high-resolution ultraviolet and visible-light observations of transient astrophysical phenomena such as gamma-ray bursts.
  • E. Far Ultraviolet Spectroscopic Explorer
    The Far Ultraviolet Spectroscopic Explorer (FUSE) was a NASA space telescope mission (1999–2007) designed to study the universe in the far-ultraviolet wavelength range, providing high-resolution spectra of stars, galaxies, and interstellar gas.
