查询词典 galaxies

Some, such as those around which galaxies are believed to accrete, formed just after the beginning of the universe.

一些黑洞，比如说其周围的星系在增长的黑洞，恰好形成于宇宙刚产生之后。

Some mergers (including NGC 2623) can result in an active galactic nucleus,where one of the supermassive black holes found at the centres of the two original galaxies is stirred into action.

包括NGC 2623在内的某些碰撞碰撞星系会形成活动星系核，形成这个过程一般会在两个原始星系的中心发现超级黑洞。

Other observations have revealed that NGC 4945 has an active galactic nucleus, meaning its central bulge emits far more energy than calmer galaxies like the Milky Way.

其他的观测资料显示， NGC4945拥有一个活动星系核，这意味着：跟象银河系这样比较平静的星系相比，其中心的凸出区域所释放的能量要多得多。

In the core of the larger spiral structure of NGC 1300, the nucleus shows its own extraordinary and distinct "grand-design" spiral structure that is about 3,300 light-years long. Only galaxies with large-scale bars appear to have these grand-design inner disks — a spiral within a spiral. Models suggest that the gas in a bar can be funneled inwards, and then spiral into the center through the grand-design disk, where it can potentially fuel a central black holes. NGC 1300 is not known to have an active nucleus, however, indicating either that there is no black hole, or that it is not accreting matter.

星系演化除了像两个星系相撞那样的剧烈作用之外，还有自己内部很慢的演化，因为一个星系总会有一些引力不稳定，如上图中的NGC1300，它是一个棒旋星系，这种bar结构导致的引力不完全对称会驱使很多气体和尘埃损失角动量往里面落，我们可以清楚的看到dust lanes，有点像黑洞的吸积，但这个星系是个非活动星系，目前还没有黑洞存在的明确证据，but我相信肯定是有的，没有比在星系中心放一个黑洞再完美不过的事情了，或许这些下落的dust lanes是黑洞发光的开始呢。

The Andromeda galaxy is the most massive in the local group of galaxies that includes our Milky Way.

蓝色的部份是年青和高温的新生恒星，而橙色的部份为年老的恒星。

But the scatter in the MLbulge correlation is substantial, and a few galaxies have anomalously large or small BHs.

但是质—光关系的数量是巨大的，并且一些星系拥有或大或小的黑洞。

Watson pondered for a minute and said, Astronomically, it tells me that there are millions of galaxies and potentially billions of planets. Astrologically, I observe that Saturn is in Leo. Horologically, I deduce that the time is approximately a quarter past three. Theologically, I can see the God is all powerful and that we are small and insignificant. Meteorologically, I suspect that we will have a beautiful day tomorrow.

华生沉思了片刻，说：从天文学的角度来说，拿说明天上有成千上万的星系，而且还可能有几十亿万颗行星；从占星学的角度来说，我观察大土星在狮子座上；从钟表学的角度来说，我估计现在时凌晨3：15；从神鞋的角度来说，我看到了神威浩大，而我们是那么的渺小而微不足道；从气象学的角度来说，我推测明天天气晴好，阳光明媚。

Astronomically, it tells me that there are millions of galaxies and potentially billions of planets.

从天文学的角度来说，这有成百万的银河系和可能潜在的数十亿的星球。

Astronomically, it tells me that there are millions of galaxies and billions of planets.

从天文学上讲，这说明又数以万计的星系于数以亿计的行星。

Watson pondered for a minute. Astronomically, it tells me that there are millions of galaxies and potentially billions of planets.

瓦特森沈思了一分钟，「就天文学而言，它告诉了我那儿有数以百万计的星系和潜在著数以千万计的星球。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
