This image shows the
Cygnus Wall, in the southern part of the North American Nebula...
NGC 7000. The emission nebula is in the constellation Cygnus, at a
distance of about 1600 light years. When shown rotated 130 degrees
CCW, the Cygnus Wall becomes the Cygnus Mountains. This area of the
Nebula, correlates geographically to southern Mexico. The famous
wall, an energized shock front, provides contrast to the adjacent
dark "Gulf of Mexico" area, filled with dark gas and dust lanes.
Discovered by William
Herschel on October 24th 1786 from Slough England.
