Target entity: Southern Galactic Cap
Context triple: [DECam Legacy Survey, skyCoverage, Southern Galactic Cap]
  • A. Northern Galactic Cap
    The Northern Galactic Cap is a large region of the sky located above the plane of the Milky Way’s disk, commonly targeted by wide-field astronomical surveys for deep imaging and mapping of extragalactic objects.
  • B. Galactic anticenter
    The Galactic anticenter is the point in the sky directly opposite the center of the Milky Way, located in the outer region of our galaxy’s disk.
  • C. Gould Belt
    The Gould Belt is a nearby, partial ring of young stars, gas, and star-forming regions tilted to the Milky Way’s plane and encompassing many of the bright constellations visible from Earth.
  • 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. Milky Way center
    The Milky Way center is the dense, energetic core of our galaxy, hosting a supermassive black hole surrounded by stars, gas, and dust.
  • F. None of above. chosen
