The North American Nebula - NGC 7000
This nebula obviously gets its moniker from its resemblance to the
continent of North America. The brightest portion corresponds to Mexico, and
the brightest region seen there is often referred to as the "Great Wall".
In many images (including some here) it is shown with its close neighbour,
the Pelican Nebula, which is part of the same nebula complex. It lies
approximately 2200 light years distant in the constellation Cygnus.
