Title: 
The Cygnus Wall of Star Formation
Explanation: 
The North America Nebula in the sky can do what North Americans on Earth cannot -- form stars. Specifically, in analogy to the Earth-confined continent [ http://www.cia.gov/cia/publications/factbook/reference_maps/north_america.html ], the bright part that appears as Central America [ http://www.cia.gov/cia/publications/factbook/reference_maps/central_america.html ] and Mexico [ http://www.cia.gov/cia/publications/factbook/geos/mx.html ] is actually a hot bed of gas, dust, and newly formed stars known as the Cygnus Wall [ http://panther-observatory.com/gallery/deepsky/doc/NGC7000_cass.htm ]. The above image [ http://www.turbinelegend.net/ASTRO/Narrowband/6-12-05/6-12-05.html ] in representative colors shows the star forming wall lit and eroded [ http://antwrp.gsfc.nasa.gov/apod/ap050424.html ] by bright young stars [ http://antwrp.gsfc.nasa.gov/apod/ap050103.html ], and partly hidden by the dark dust [ http://antwrp.gsfc.nasa.gov/apod/ap030706.html ] they have created. The part of the North America nebula [ http://antwrp.gsfc.nasa.gov/apod/ap000501.html ] (NGC 7000) shown spans about 15 light years [ http://chandra.harvard.edu/photo/cosmic_distance.html ] and lies about 1,500 light years away toward the constellation [ http://en.wikipedia.org/wiki/Constellation ] of Cygnus [ http://www.astronomical.org/portal/modules/wfsection/article.php?articleid=31 ].
