Target entity: Eridanus Supervoid
Context triple: [Eridanus, containsDeepSkyObject, Eridanus Supervoid]
  • A. Shapley Supercluster
    The Shapley Supercluster is one of the most massive known concentrations of galaxies in the nearby universe, exerting a significant gravitational influence on surrounding cosmic structures.
  • B. Perseus–Pisces Supercluster
    The Perseus–Pisces Supercluster is a massive, elongated concentration of galaxy clusters stretching hundreds of millions of light-years across space and forming one of the most prominent large-scale structures in the nearby universe.
  • C. Laniakea Supercluster
    Laniakea Supercluster is a vast cosmic structure encompassing the Milky Way and hundreds of thousands of other galaxies, forming one of the largest known galaxy superclusters in the observable universe.
  • D. Great Attractor region
    The Great Attractor region is a massive gravitational anomaly in intergalactic space that strongly influences the motion of nearby galaxy clusters, including those in the Hydra–Centaurus Supercluster.
  • E. Hydra–Centaurus Supercluster
    The Hydra–Centaurus Supercluster is a massive nearby concentration of galaxy clusters that forms one of the dominant structures in our cosmic neighborhood and serves as a major component of the larger Laniakea Supercluster.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
