Above, two different views of the North American Nebula rest neatly- the first showcases what is familiar to the human eye, and the second shows the view in infrared (whose primary source is energy). The North American Nebula (named for its resemblance to the continent in the visible spectrum) is a star-birthplace.As they form mostly in the dust regions, it has been difficult to see detail in the past. The Spitzer Space Telescope  took this image and is the final mission in NASA's Great Observatories program. The North American Nebula lies near Cygnus.
