星系

Located 300 million light-years away in the constellation Coma Berenices, the colliding galaxies have been nicknamed "The Mice" because of the long tails of stars and gas emanating from each galaxy.

这对正在碰撞的星系有个外号叫&老鼠星系&，因为他们拖着由星体和气体散发形成的长长的尾巴。

MCG+08-11-002 is an odd-looking galaxy with a spectacular dark band of absorbing dust in front of the galaxy's center, making it resemble a "Black Eye".

MCG+08-11-002是一个单体星系，在星系中心有着壮观的尘埃吸收带，使其看上去像是一个&黑眼睛&。

But I said there were a couple of ways to use neighboring constellations to find the Andromeda galaxy.

我说过利用邻近星系可以有很多种方法来寻找仙女座星系。

In the current paradigm of galaxy formation, disk galaxies are assumed to form by the cooling and condensation of baryons within dark matter halos.

目前的星系形成理论认为，盘状星系由暗晕中的重子物质冷却并坍缩而成。

By studying galaxies at different epochs, astronomers can see how galaxies change over time.

通过研究星系的不同时期，天文学家能够观测星系整个的演化过程。

NGC 3808 is a nearly face-on spiral galaxy with a bright ring of star formation and several prominent dust arms.

NGC 3808是一个星系盘面几乎朝向我们的漩涡星系，由一个明亮的恒星环和数条显著的尘埃旋臂构成。

AM 0500-620 consists of a highly symmetric spiral galaxy seen nearly face-on and partially backlit by a background galaxy.

AM 0500-620 由一个高度对称的几乎正面朝向的漩涡星系和一个被部分遮挡&背光&样的背景星系组成。

ESO 550-2 shows a pair of spiral galaxies, the larger nearly face-on and accompanied by a smaller, highly tilted partner.

ESO 550-2展现了一对漩涡星系，一个较大的几乎面对我们的和一个较小的高度倾斜的星系。

In fact, from a vantage point that viewed our galaxy face-on, astronomers in distant galaxies would likely see the Milky Way as a two-armed barred spiral similar to this artist's illustration.

事实上，如果天文学家从一个有利的位置朝我们银河系观看，那么从遥远星系上看到我们银河系是一个具有两条旋臂的棒旋星系，就像这张艺术家的插图一样。

The NGC 1532/1531 pair is thought to be similar to the syst em of face-on spiral and small companion known as M51, the Whirlpool Galaxy.

一般咸信NGC 1532/1531星系对的架构，应和正面对著我们的螺旋和小星系对M51很相似。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
