Good morning. It's January 16, and today we travel 2,600 light-years out into space to the Cygnus Wall.
Although this sounds like some kind of barrier between galaxies, the name Cygnus Wall has a more mundane origin, as it looks like a wall and is located in the constellation Cygnus. It's the brightest region of the so-called North American Nebula, which in some images looks like the outline of North America.
The Cygnus Wall, if you use your imagination, looks a bit like Central America and Mexico. It is an active star-forming region with lots of hydrogen and sulfur, which produce the red colors in this image, and oxygen, shown in blue. This feature is about 20 light-years across, or more than six times the diameter of our solar system.
