BH in our galaxy

    If there is a black hole at the center of our galaxy, why does the center of our galaxy looks so bright?

    1. the black hole is not the only resident
    2. matter inspiralling into the central black hole radiates strongly

    The black hole at the center of our galaxy, despite being massive, is absolutely tiny on the galactic scale. The radius of the black hole in the center of our galaxy is on the order of a couple of tens of AU (1 AU = the distance from the earth to the sun). Seen from the earth, this is absolutely tiny.
