good morning. January 16th Today we travel 2,600 light-years out into space toward the walls of the constellation Cygnus.
Although this sounds like some kind of intergalactic barrier, the Cygnus wall nomenclature has more mundane origins. It looks like a wall and is located in the constellation Cygnus. It is the brightest region of the so-called North America Nebula, and in some photos it looks like the outline of North America.
If you use your imagination, the walls of Cygnus resemble those of Central America or Mexico. It is a region of active star formation, rich in hydrogen and sulfur, which gives the image a reddish hue, and oxygen, shown in blue. The diameter of this terrain is about 20 light years, or more than six times the diameter of the solar system.
Mel Martin sent us this image taken from his backyard observatory in Arizona. Lovely.
