Cygni Valleys in honor of the star N. M. L. Cygni

I call them Cygni Valleys in honor of the star N. M. L. Cygni, a hyper-giant star that is the second-largest star known to us. The star is so large that it outshines our Sun 272,000-fold.

The star is 1,183-times larger than our Sun and has 20-50 times its mass contained in 1.65 billion times its volume.
