恒星

Gravitational violence during mergers mixes orbits and redistributes energies and angular momenta; the result is that quiescently formed systems such as disks are turned into ellipsoids.

合并期间引力作用混合了彼此的恒星并且重新分配了角动量；其结果是被迫合并的系统变成了椭圆星系。

In this paper the phase shifts in spiral galaxies M 81 and M 51 has been computed. It is found that the theoretical patterns of the spiral arms agree in general with the observational results of 21 cm radio emission in the main.

本文具体计算了M81，M51两星系的恒星臂与气体臂之间的相移，给出了两星系的星臂乃气臂的式样，与21厘米射电观测结果比较表明，理论与观测基本上是符合的。

Cen A, also known as NGC 5128, is also unusual compared to an average elliptical galaxy because it contains a higher proportion of young blue stars and is a very strong source of radio emission. Evidence indicates that Cen A is likely the result of the collision of two normal galaxies.

又名为NGC 5128的半人马座A和寻常椭圆星系的其他差异有：较高比例的年轻蓝色恒星和会发出很强的电波辐射，这些证据指向半人马座A是二个正常星系互撞后的产物。

The messenger of the electromagnetic force is the photon with zero mass; the weak force that accounts for radioactive disintegration and causes the sun and the stars to shine is carried by the heavy W and Z boson particles; while the strong force is carried by gluon particles, which see to it that the atom nuclei hold together.

电磁力的信使是零质量的光子，弱作用力可以用来说明辐射衰变和太阳和恒星发光，其信使是重W和Z玻色子。

J. Moffat, all from CRAQ (Centre de recherche en astrophysique du Québec), a center belonging to the University of Montreal in Canada, have broken that record twice.

星云中所有的恒星几乎有相同的年龄，即100万年，但这与我们有50亿年寿命的太阳和太阳系相比，只是一眨眼的时间。

China's stellar reconnaissance camera is used to accurate determination of satellite and the location of ground targets.

中国侦察卫星上的恒星相机是用来精确测定卫星及地面目标的位置的。

Partly it has great practical value – you can wrap it around you for warmth as you bound across the cold moons of Jaglan Beta; you can lie on it on the brilliant marble-sanded beaches of Santraginus V, inhaling the heady sea vapours; you can sleep under it beneath the stars which shine so redly on the desert world of Kakrafoon; use it to sail a mini raft down the slow heavy river Moth; wet it for use in hand-to-hand-combat; wrap it round your head to ward off noxious fumes or to avoid the gaze of the Ravenous Bugblatter Beast of Traal (a mindboggingly stupid animal, it assumes that if you can't see it, it can't see you – daft as a bush, but very ravenous); you can wave your towel in emergencies as a distress signal, and of course dry yourself off with it if it still seems to be clean enough.

一方面是由于它有着非常实际的使用价值——当你跳跃着穿越Jaglan Beta的冰冷的月亮中间时，可以把毛巾裹在身上用来取暖；在Santraginus V的灿烂的大理石沙子的海滩，你也可以躺在毛巾上，呼吸浓烈醉人的海洋蒸汽；也可以在Kakrafoon的沙漠世界里，在红色的恒星照耀下，盖着毛巾睡觉；用它做帆，在缓慢宽阔的Moth河上泛舟；在近身搏斗中打湿了做武器；包住脑袋来防止毒气侵袭或者避开Traal的贪婪虫鸣兽的喋喋不休（一种发自内心的愚蠢的动物，它总是认为如果你看不到它，它也就看不到你——蠢得像灌木，却很贪婪）；可以在紧急情况下挥动毛巾表示求救信号；当然，也可以用来擦干身体——如果它看起来还是足够干净的话。

Newton also developed the reflecting telescope .

更广泛的恒星目录制作了Lacaille 。

He began examining nearby galaxies with a 10-inch refractor to see whether any stars had flared up.

他用口径10英寸的折射望远镜巡视邻近的星系，查看是否有恒星已经闪亮。

He began examining nearby galaxies wi a 10-inch refractor to see whether any stars had flared up.

他用口径10英寸的折射望远镜巡视邻近的星系，查看是否有恒星已经闪亮。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
