How Far Away is That Galaxy? NED-D

  • Budgieye by Budgieye moderator

    A team of researchers has compiled a special catalog to help
    astronomers figure out the true distances to tens of thousands of
    galaxies beyond our own Milky Way.

    The catalog, called NED-D, is a critical resource, not only for
    studying these galaxies, but also for determining the distances to
    billions of other galaxies strewn throughout the universe. As the
    catalog continues to grow, astronomers can increasingly rely on it for
    ever-greater precision in calculating both how big the universe is and
    how fast it is expanding. NED-D is part of the NASA/IPAC Extragalactic
    Database (NED), an online repository containing information on more
    than 100 million galaxies.
