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。

However, Green (1996, p.5) provides useful elaboration by definition when he stated,"Semantics is compositional and is basically truth conditional." As Poole (2000, p.11) states,"the disparity between what we intend to communicate and what we actually say is central to pragmatics." But in the above example use of "failure" in respect to a friend, what if the addressor was trying to be ironic and or slightly comical within an appropriate context.

不过，格林(1996，p.5)提供了有用的拟订的定义，他说，"语义成分，而且基本上是真理有条件"作为poole(2000，p.11)，"之间的差距，我们打算进行沟通，其实我们说的是中央对语"但在上述例子中使用"失败"，对于朋友，假如addressor正在设法予以讽刺或略有滑稽在一个恰当的背景。
