NGC 6326 NGC 6326 is a complex and irregularly structured planetary nebula located in the constellation Ara. It is designated as PN in the galaxy morphological classification scheme and was discovered by the Scottish astronomer James Dunlop on 26 August 1826. NGC 6326 is the result of the ejected material from the central binary star, which is nearing the end of its life. The blue and red color is due to the amount of radiation the star releases, thus causing the gasses to glow. NGC 6326 is located at about 11,000 light years away from earth.
