• A. Extreme Ultraviolet Explorer
  Extreme Ultraviolet Explorer was a NASA space telescope mission that operated in the extreme ultraviolet wavelength range to study hot stars, white dwarfs, and the interstellar medium.
• B. Chandra X-ray Observatory
  The Chandra X-ray Observatory is a space-based telescope that observes high-energy X-ray emissions from hot regions of the universe, such as exploded stars, galaxy clusters, and matter around black holes.
• C. International Ultraviolet Explorer
  The International Ultraviolet Explorer was a space telescope launched in 1978 that provided pioneering ultraviolet observations of astronomical objects for nearly two decades.
• D. Infrared Astronomical Satellite
  The Infrared Astronomical Satellite (IRAS) was a pioneering space telescope launched in 1983 that conducted the first-ever all-sky survey at infrared wavelengths, dramatically expanding knowledge of stars, galaxies, and cosmic dust.
• E. Compton Gamma Ray Observatory
  The Compton Gamma Ray Observatory was a NASA space telescope dedicated to observing high-energy gamma-ray emissions from cosmic sources, significantly advancing our understanding of phenomena like gamma-ray bursts, pulsars, and active galactic nuclei.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
