15:4.7 Not all [http://www.wikipedia.org/wiki/Spiral_Nebula spiral nebulae] are engaged in sun making. Some have retained [[control]] of many of their segregated stellar offspring, and their spiral appearance is occasioned by the fact that their suns pass out of the nebular arm in close formation but return by [[diverse]] routes, thus making it easy to observe them at one point but more difficult to see them when widely scattered on their different returning routes farther out and away from the arm of the nebula. There are not many sun-forming nebulae active in [[Orvonton]] at the present time, though [[Andromeda]], which is outside the inhabited superuniverse, is very active. This far-distant nebula is visible to the naked eye, and when you view it, pause to consider that the light you behold left those distant suns almost one million years ago. | 15:4.7 Not all [http://www.wikipedia.org/wiki/Spiral_Nebula spiral nebulae] are engaged in sun making.
