Caption:: Located in the constellation Herculues, M13 is the largest and brightest globular cluster in the northern sky,位于武仙座的球状星团M13，是北天球最大最亮的球状星团，在全天排行第三，仅次于南天球的半人马座奥米加星团，杜鹃座47。
For example, if we knew that computer programs 0, 10 and 110 all halt, then we would know that the first digits of omega举例来说，如果知道程式0、10、110会停止，就可以知道Ω的前面几位数是0.111。
For the case where Omega is exactly equal to one, the Universe is delicately balanced between the two states, and is sai对于欧米加正好等于平均数的情形，宇宙微妙地在二种情形之间平衡,就被说成是“扁平”。
If the Universe is closed, Omega is greater than unity, and the Universe will eventually stop its expansion and recollap如果宇宙是封闭的,欧米加大于平均数，而且宇宙最终会停止它的膨胀及重新往回坍缩自己。
It and OMEGA have revealed a diversity of igneous rock compositions that rivals Earth's.它与OMEGA揭露出各形各色的火成岩组成，足与地球上的媲美。
