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. It is sometimes incorrectly called the “North American Nebula”. 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.
