困难词：外星人（来自地球之外）、喧闹（大量噪音）、类星体（产生大量能量和光非常大恒星）。机翻

17.These include active galactic nuclei, and quasars which are thought  to be the accretion disks of supermassive black holes, and also ultraluminous x-ray sources  thought to be from intermediate mass black holes.

这包括活跃星系核和类星体，它们被认为是超大质量黑洞吸积盘，以及被认为来自中等质量黑洞超亮X射线源。机翻

18.Almost all the telescopes we have in the world are designed to peer at very tiny little pieces of the sky way off in the distance to see a quasar or hunt for black holes or look at a distant galaxy.

世界上差不多所有望远镜都旨在观察遥远天空中极小东西，观察颗类星体，或寻找黑洞，或观察个遥远星系。

19.I didn't know what a proton was, or a protein, didn't know a quark from a quasar, didn't understand how geologists could look at a layer of rock on a canyon wall and tell you how old it was, didn't know anything really.
