By performing a detailed analysis of the hst images , kwok and hsia found a series of nine rings along the axis of this hourglass - shape nebula . these mysterious rings are circular in shape and lined up precisely one after another 郭新教授和夏志浩详细分析这些照片时，发现有九个神秘的环，一个接一个的环绕著这星云的轴心。
When the moon in opposition to the sun is joined with nebulous stars , the native will have some defect in his sight ; if the moon in the seventh be afflicted by both the infortunes , and if their rays are very strong he will be blind 盘中月亮与太阳对冲，且伴有星云的影响，会对盘主的视力造成障碍；若月亮落在第7宫同时被凶星和星云刑伤，且凶星影响力很强时，则存在致盲的可能。
The 9th power of the 9th power of 9 , that , the result having been obtained , 33 closely printed volumes of 1000 pages each of innumerable quires and reams of india paper would have to be requisitioned in order to contain the complete tale of its printed integers of units , tens , hundreds , thousands , tens of thousands , hundreds of thousands , millions , tens of millions , hundreds of millions , billions , the nucleus of the nebula of every digit of every series containing succinctly the potentiality of being raised to the utmost kinetic elaboration of any power of any of its powers 所得数字要用细字密密匝匝地印刷成三十三卷，每卷一千页。为了统统印刷完毕，就需要购入无数刀无数令印度纸，整数值的位数便是一十百千万十万百万千万亿十亿，一切级数的一切数字作为星云的核心，以简明的形式所包含的累乘的可能性推到了极限地能动地开展的一切乘方的一切幂级数。
The poem swung in majestic rhythm to the cool tumult of interstellar conflict , to the onset of starry hosts , to the impact of cold suns and the flaming up of nebular in the darkened void ; and through it all , unceasing and faint , like a silver shuttle , ran the frail , piping voice of man , a querulous chirp amid the screaming of planets and the crash of systems 那诗以庄重的节奏振荡起伏，伴随着星际冲突的清冷的波涛万千星宿的前进步伐和无数冷冰冰的太阳的冲击，伴随着最黑暗的空虚望的星云的燃烧而在这一切之间，却传来了入类微弱细小的声音，有如一支银梭，不断地无力地呐喊着，在星球的呼啸和天体的撞击声中只不过是几声哀怨悲嗟的唧唧啾鸣。
Today many astronomers believe that the various forms seen in planetary nebulae can be explained by one model that we see from different angles . if we sight down the axis of the flow , we see a round nebula like the ring . looking from " above " , the bipolar flows are conspicuous , as with ngc 6302 天文学家相信行星状星云的不同形态是基于在不同的观测角度下的视觉效果，若沿著恒星风吹出的方向望去，则会看见像戒指星云的结构在顶端观看，行星状星云有明显的双极结构例如行星状星云ngc6302 ，而在界乎两者之间，则会看到像行星状星云ngc2346的结构。
Prof . sun kwok , chair professor and dean of science at the university of hong kong , believes that the rings seen in hubble 12 are related to the shaping of the nebula : " a series of fast , directional , periodic pulse ejections from the star carve out the remnants of previously ejected material and create the hourglass shape 郭教授相信，这些从哈勃12号星云观测所见的层圈，和星云的形成不无关系。一连串高速周期性有方向性的爆发，将哈勃12号星云雕刻成这漏斗形状。
To circumvent this problem , advocates of 26al heating hypothesize that some chondrules might have formed earlier in the solar system ' s history ? perhaps closer to the time when the minerals in the refractory inclusions condensed from the solar nebula ? and thus had much higher 26al to 27al ratios 为了解决这个问题，铝26加热说的拥护者假设，某些球粒可能是在太阳系历史的更早期形成，也许与耐火包体开始由太阳系星云的收缩而形成的时间差不多，因此铝26对铝27的比值较高。
