NGC 1566, a galaxy located about 40 million light-years away in the constellation of Dorado. According to NASA, the NGC 1566 is an intermediate spiral galaxy. That means while the NGC 1566 does not have a well defined bar-shaped region of stars at its center, like barred spirals, it is not quite an unbarred spiral either. The small but extremely bright nucleus of the NGC 1566 is clearly visible in this image, a telltale sign of its membership of the Seyfert class of galaxies. The centers of such galaxies are very active and luminous, emitting strong bursts of radiation and potentially harboring supermassive black holes that are many millions of times the mass of the Sun. NGC 1566 is the second brightest Seyfert galaxy known. It is also the brightest and most dominant member of the Dorado Group, which is a loose concentration of galaxies that collectively comprise one of the richest galaxy groups of the southern hemisphere.
