     {Zodiacal light}, a luminous tract of the sky, of an


        elongated, triangular figure, lying near the ecliptic, its
        base being on the horizon, and its apex at varying
        altitudes. It is to be seen only in the evening, after
        twilight, and in the morning before dawn. It is supposed
        to be due to sunlight reflected from multitudes of
        meteoroids revolving about the sun nearly in the plane of
        the ecliptic.
