Yucatan, North America Nebula, NGC7000


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 ofNorth America, complete with a prominent Gulf of Mexico. It is sometimes incorrectly called the “North AmericanNebula”. It is in the left part of the photo. The entire nebula has an area of more then four times the size of the full moon, but the field of view of this image is just a fraction of the nebula – an area of less then half a full moon, centered near the “Yucatan” part of North America.
