The North America and Pelican Nebulae (NGC 7000 / IC 5070)
NGC 7000 and IC 5070 form one of the largest emission-nebula complexes in the constellation Cygnus. Known as the North America and Pelican Nebulae for their distinctive outlines, they lie roughly 2,600 light-years from Earth and belong to the same vast region of ionized gas and active star formation. The dark structures that appear to separate the two nebulae are not empty spaces. They are dense clouds of interstellar dust lying in front of the glowing gas and obscuring the light behind them.
Beyond the frame
The colors in this image do not represent how the region would appear to the human eye. The image is built from narrowband exposures that isolate emission from ionized hydrogen, oxygen, and sulfur. By assigning these signals to different color channels, structures that would otherwise be difficult to distinguish become separated visually. Color therefore becomes more than an aesthetic choice: it is a way of revealing the physical structure of the region — where different gases emit, where dust obscures the light, and where radiation from young stars is shaping the surrounding material.
