North American Nebula

[′nȯrth ə′mer·i·kən ′neb·yə·lə]
(astronomy)
A cloud of dust and gas in the constellation Cygnus; the density of this gas and dust is possibly a thousand times greater than the average density of interstellar gas; a much denser cloud of dust between the nebula and earth obscures portions of the emission nebula to create the appearance of the “Gulf of Mexico” and the “Atlantic Ocean.”
