Target entity: Chandra X-ray Observatory
Context triple: [Trifid Nebula, observedBy, Chandra X-ray Observatory]
  • A. Chandra X-ray Observatory chosen
    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.
  • B. 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.
  • C. 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.
  • D. RXTE
    RXTE (Rossi X-ray Timing Explorer) was a NASA satellite observatory dedicated to studying time-variable X-ray sources such as neutron stars, black holes, and active galactic nuclei.
  • E. 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.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
