This is the best summary I could come up with:

It’s January 16, and today we’re traveling 2,600 light-years outward into space to the Cygnus Wall.

Although this sounds like some kind of intergalactic barrier, the Cygnus Wall’s nomenclature has a more mundane origin—it looks like a wall and is located in the Cygnus constellation.

The Cygnus Wall, if you use your imagination, somewhat resembles Central America and Mexico.

It is a region of vigorous star formation with lots of hydrogen and sulfur, which produce the reddish hues in this image, and oxygen, shown in blue.

This feature measures about 20 light-years across, or more than six times the diameter of our Solar System.
