NuSTAR Nuclear Spectroscopic Telescope Array

Target entity: NuSTAR Nuclear Spectroscopic Telescope Array
Context triple: [NASA Astrophysics Division, overseesMission, NuSTAR Nuclear Spectroscopic Telescope Array]

• A. Fermi Gamma-ray Space Telescope
  The Fermi Gamma-ray Space Telescope is a NASA space observatory that studies the universe in high-energy gamma rays, revealing phenomena such as black holes, neutron stars, and gamma-ray bursts.
• B. Neil Gehrels Swift Observatory
  The Neil Gehrels Swift Observatory is a NASA space telescope dedicated primarily to detecting and studying gamma-ray bursts and other high-energy astrophysical phenomena.
• C. 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.
• D. IXPE X-ray Polarimetry Explorer
  IXPE X-ray Polarimetry Explorer is a NASA space observatory designed to measure the polarization of cosmic X-rays to study extreme astrophysical environments such as black holes, neutron stars, and supernova remnants.
• E. NICER Neutron star Interior Composition Explorer
  NICER (Neutron star Interior Composition Explorer) is an X-ray astronomy instrument mounted on the International Space Station that studies neutron stars to probe their ultra-dense interiors and extreme physics.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
