Why Dark Horse
This region of dark nebulae is called Dark Horse because it resembles the side silhouette of a horse and appears dark as compared with the background glow of stars and star clouds. It is also known as "Great" because it is one of the largest (in apparent size) groups of dark nebulae in the sky.

Famous quotes containing the words dark and/or horse:
“—the dark ajar, the rocks breaking with light,
and undisturbed, unbreathing flame,
colorless, sparkless, freely fed on straw,
and, lulled within, a family with pets,
—and looked and looked our infant sight away.”
—Elizabeth Bishop (1911–1979)
“I on my horse, and Love on me, doth try
Our horsemanships, while by strange work I prove
A horseman to my horse, a horse to Love,”
—Sir Philip Sidney (1554–1586)
