NGC 1566

NGC 1566, sometimes known as the Spanish Dancer,[3][4] is an intermediate spiral galaxy in the constellation Dorado. It is the dominant and brightest member[5] of the Dorado Group,[6][7] being among the brightest Seyfert galaxies in the sky.[5] Absolute luminosity is 3.7×1010 L☉,[8] and is calculated to contain 1.4×1010 M☉ of H I.[8]
