恒星

The third is the remote globular star cluster NGC 2419, at distance of nearly 300,000 light-years.

其中两个是附近的恒星，第三个就是距离我们30万光年之远的球状星团NGC 2419。

Globular cluster is a group of tens of thousands to millions of stars bounded under gravity.

球状星团由上万至百万的恒星组成，在一个细小范围内由万有引力维系的集团。

And together with gravitational constant G, over 50 other scientific units depend on stars position!

质量随其绝对运动速度的改变而改变，同时一起变化的还有万有引力常数G，以及超过50个由恒星位置决定的科学单位！

In treating this kind of gaseous motion, the gravitational potential is primarily determined by the stars or central object.

旋涡星系盘和原始太阳星云盘都是由两种成份组成：气体和恒星。

2 The idea is that the matter we say does not have enough gravitational pull to keep galaxies together.

这种概念源自我们所说的物质没有足够的引力把恒星束缚在星系内部。

Spiral galaxies are considered to be gravitationally bound configurations of stars.

旋涡星系被认为是由恒星组成的引力束缚系统。

A galaxy is a system of many stars and gas that is gravitationally bound in a dark matter halo.

星系是许多恒星和气体构成的系统，在一个暗晕里面通过引力束缚在一起。

We define a first galaxy as one comprised of the very first system of stars to be gravitationally bound in a dark matter halo.

我们这样来定义第一代星系，即由非常早期的恒星系统在暗晕中被引力束缚在一起。

For 13 years, astronomers have been finding exoplanets using ground-based telescopes to monitor the subtle wobble a planet gravitationally induces in its star.

这个可靠的径向速度技术对发现靠近主恒星的巨大而炽热的"热木星"尤其有效。

Professor Bainbridge leads the Fine Art area at Sunderland and in this work references to planets and the stars built out of huge Cast Iron spheres again draws upon traditional craft skills of the region and turns an ordinary traffic roundabout to a gateway to the town of Hartlepool.

Bainbridge 教授是森德兰地区美术界的领导者，这部作品指涉行星和恒星，由巨型铸铁球完成。制作过程中，艺术家们也是吸取这个地区传统的工艺技巧，它被安放在一个普通的交通环形道，从而把这个地方变成了通往 Hartlepool 的大门。

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。
