This image, created with the Very Large Array telescope, maps the radio emission of neutral hydrogen in NGC 784. Compare it with the neutral hydrogen map of the “face-on” galaxy M83. There the spiral arms are clearly visible. The bright spots on either side of NGC 784’s center may be the spiral arms seen from the side. 
    The large concentration of neutral hydrogen gas in NGC 784’s center may reside in the central bulge, which is otherwise not visible. If this is so, the galaxy’s center is very different from that of M83, which contains little neutral hydrogen.
