In recent years our Standard Model of Cosmology was confirmed and established by numerous observations. Starting from a very dense and hot initial state, called Big Bang , the universe expanded and thereby cooled. During this expansion, large-scale structures have formed, which can be observed as galaxies and quasars today. Due to enormous improvements in the technology of modern telescopes and instruments, it is now possible to examine these cosmic objects even at extremely large distances, and therefore we are able to observe them in the universe when it was much younger than today.

近年来，我们的宇宙学标准模型通过大量观测得到证实和建立。从一个非常稠密和炎热的初始状态（称为大爆炸）开始，宇宙膨胀并因此冷却。在这次膨胀过程中，形成了大规模的结构，今天可以观察到星系和类星体。由于现代望远镜和仪器技术的巨大进步，现在即使在极远的距离也可以检查这些宇宙物体，因此我们能够在比今天年轻得多的宇宙中观察它们。
