    • Hubble Source Catalog Summary Search

    Metadata Updated: March 13, 2026

    The Hubble Source Catalog (HSC) is designed to optimize science from the Hubble Space Telescope \nby combining the tens of thousands visit-based source lists in the Hubble Legacy Archive (HLA) \ninto a single master catalog. \nThe HSC Summary search displays a single row entry for each object,\nas defined by a set of detections that have been cross-matched and hence are believed to be a single object.\nAveraged values for magnitudes and other relevant parameters are provided.\nThe catalog currently contains over 16 million entries.
