Phrase: COS-B (U.S. participation) | Statement: [NASA astrophysics observatories, includes, COS-B (U.S. participation)]

Target entity: COS-B (U.S. participation)
Context triple: [NASA astrophysics observatories, includes, COS-B (U.S. participation)]

• A. 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.
• B. Cosmic Background Explorer
  The Cosmic Background Explorer (COBE) was a NASA satellite mission that made precise measurements of the cosmic microwave background radiation, providing key evidence for the Big Bang theory and earning its scientists the Nobel Prize in Physics.
• C. Einstein Observatory
  The Einstein Observatory was NASA’s first fully imaging X-ray telescope in space, pioneering high-resolution X-ray astronomy of cosmic sources.
• 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. Uhuru X-ray satellite
  The Uhuru X-ray satellite was the first Earth-orbiting mission dedicated to X-ray astronomy, pioneering the systematic study of cosmic X-ray sources and laying the foundation for modern high-energy astrophysics.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
