Image details:
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 shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico.
The portion of the nebula resembling Mexico and Central America is known as the Cygnus Wall. This region exhibits the most concentrated star formation.
Data show that the North America Nebula lies 2,590 light years away (795±25 parsecs). The whole HII region Sh2-117 is then 140 light years across,
and the North America Nebula stretches 90 light years north to south. (Information from Wikipedia)
