 The DR 6 cluster is also nicknamed the "Galactic Ghoul" because of the nebula's resemblance to a human face; astronomers have described it as "some sort of freakish space face," emphasizing the cavity-like regions that look like eyes and a mouth.These large cavities are the result of "energetic light" and strong stellar wind that come from the ten stars in the center of the nebula (the part also known as the "nose").Because of the nebula's spooky appearance, it was featured on the NASA website as the Astronomy Picture of the Day on All Hallows Eve, November 1, 2004.
