Description

The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus, close to Deneb (the tail of the swan and its brightest star).

The remarkable shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico. The nebula is large, covering an area of more than four times the size of the full moon; but its surface brightness is low.

Cygnus's Wall is a term for the "Mexico and Central America part" of the North America Nebula. The Cygnus Wall exhibits the most concentrated star formations in the nebula.

The distance of the nebula complex is not precisely known, nor is the star responsible for ionizing the hydrogen so that it emits light.
