Three giant star-dust "wedding rings" in the Milky Way, in the form of planetary nebulae, probably hundreds of times larger than the solar system, have been discovered in the southern sky by Mrs. Muriel M. Seyfert, Research Assistant of the Observatory staff.

Although there are not sufficient data to permit accurate calculation of the size and distance of the new nebulae, the observers believe that like most of the 130 known planetary nebulae, these found by Mrs. Seyfert are several hundred light years distant from the earth.
