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。

Actually, i am very worried about you...

或许，是我的问题。。

For an instant, the gaze of the horror-stricken multitude was concentred on the ghastly miracle; while the minister stood, with a flush of triumph in his face, as one who, in the crisis of acutest pain, had won a victory.

Third, as to his relationships with the rest of the planet, the sceptics may repeat ad nauseam that an Obama presidency will not change America's status as a hyperpower and the disapproval that power evokes.

第三，至于他与地球上其它地区的关系，怀疑论者或许不断令人生厌地重复，奥巴马当选总统将不会改变美国作为超级强国的地位，以及由实力引起的反对。

As a matter of fact,you even had no idea about the words or praise he said to you.Perhaps,it was an ad-lib joke of his,or just a sentence from a textbook,which,however,you accepted as ture.

It tends to sound admonitory and joyless: you might expect a doctor or an insurance company to urge you to take more exercise.

它听起来总带有惩戒和无趣的意味：或许你也能想得到，医生或是保险公司常会督促你多加锻炼。
