Or the Pelican Nebula IC 5067 is an emission nebula in the constellation of Cygnus, near Deneb (α Cygni), and separated from the larger nebula NGC 7000 by a dark region. The dark area is called the Gulf of Mexico, as in some astronomical plates for many years seemed to be that region of the Earth. Both nebulae, IC 5070 and NGC 7000, are part of the same H II region. Inside the Pelican Nebula, dark dust clouds also help define the eye and long bill, while a bright front of ionized gas suggests the silhouette of the head and neck. The nebula is physically located in the rear of the serious neck is actually known as IC 5070, but is better known as the "neck".

The Lagoon Nebula (also known as Messier Object 8, Messier 8, M8 or NGC 6523) is an emission nebula (specifically it is an H II region), located in the constellation Sagittarius. Is approximately at a distance of 5200 light years. It was discovered by Guillaume Le Gentil in 1747. The nebula, a molecular cloud associated with and forming part of the Sagittarius OB1 stellar association, seems to have a depth comparable to its width and includes a number of Bok-globules of gas and dust clouds in the process of collapse to form stars - some of which have been cataloged by Edward Emerson Barnard how B88, B89 and B296. In the center of the nebula is a structure known as the hourglass, which is an intense activity of star formation, in which, in the year 2006 have been identified four Herbig-Haro objects [1] [ 2]. It also includes a structure shaped like a tornado caused by a star of type O.
