引力

A galactic cluster is an group of galaxies which are gravitationally bound.

银河星团是一组受引力约束的银河。

Andromeda is so close, in fact, that it is gravitationally bound to the Milky Way, and is one of the only galaxies in the sky that is moving toward us.

实际上，她离我们如此的近，以至于它的引力已经影响到银河系，它是天际中唯一朝向我们移动的星系。

Most galaxies are found in gravitationally bound groups, called clusters.

大多数星系发现于各个靠引力维系的集团内，也成为星系团。

Q0957+561 is a quazar whose image is gravitationally lensed by a galaxy which lies directly in the line of sight between it and our own world.

q0957 561是一个quazar的形象是引力透镜由银河在于直接在瞄准线之间，它和我们自己的世界。

Because the planet is so close to the star, it is gravitationally locked to it in the same way the Moon is locked to Earth.

由于这颗行星距其恒星太近，引力把它束缚在恒星周围，就如同月球被束缚在地球周围一样。

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。

The dark matter only interacts gravitationally and so it stays at the center of the sound wave, the origin of the overdensity.

暗物质仅通过引力进行相互作用，所以其呆在声波的中心，也即声波起源的高密度区域。

By the year 3,000,000,000,000, all that will be left for astronomers to observe will be the stuff that today makes up our gravitationally bound 'local group' of galaxies: the Milky Way and Andromeda, the Large and Small Magellanic Clouds , and a few other puny galaxies.

到公元3，000，000，000，000年，天文学家所能够观察到的将只剩下我们的本星系团，其中的星系由引力束缚在一起，包括：银河系和仙女座、大小麦哲伦星系和其他几个小星系。

Sirius B has a super-heavy gravitationally powerful star made of concentrated super-dense matter with the number 50 associated with it.

天狼星B具有50号以超密度物质组成的超重力引力星。

While overdensity gravitationally attracts matter towards it, the heat of photon-matter interactions creates a large amount of outward pressure.

尽管高密度区域通过引力将物质吸引向自己，光子和物质相互作用的加热产生了强大的向外的压强。

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。
