Enlil was the Sumerian god of the earthly skies and thus the master of weather and the winds. These winds bore different characteristics and were responsible either for draughts and famines or bountiful harvests and abundancy. Consequently, Enlil was always regarded as being a bit wayward, at one time even trying to drown mankind in a great flood.

The astronomical Winds of Enlil are a wayward object, too, and a bit of a conundrum, since many characteristics associated with a 'classic' nebula seem to be missing. First, the Winds do not have a core element like a stellar corpse from which the Winds may have originated. This alone would not pose too much of an explanatory problem but the complex also barely has any massive young stars or protostar population that would hint at star formation taking or having taken place. Instead, most stars inside the complex are rather old M and K type stars that are from 1.5 to 6.8 billion years old. This may indicate that the Winds of Enlil are in fact moving through the area, presumably being pulled in by the Milky Way's gravity. A strong indicator for this theory is the fact that the Winds seem to be compressed or flattened at the top: Dust and gas accumulate here and the Winds' movement seems to be stalled. So what we see here may in fact be the formation of a dust cloud that will eventually turn into a Stellar Nursery in a couple of million years. (Further references)
