The Pillars of Creation
The Horsehead
The Hubble Space Telescope (HST), named after astronomer Edwin Powell Hubble, is a telescope that orbits the Earth in orbit.
哈勃空间望远镜（缩写为HST），以天文学家爱德温·哈勃（Edwin Powell Hubble）为名，在轨道上环绕着地球的望远镜。
哈勃空间望远镜的位置在地球的大气层之上，因此获得了地基望远镜所没有的好处-影像不会受到大气湍流的扰动，视相度绝佳又没有大气散射造成的背景光，还能观测会被臭氧层吸收的紫外线。
哈勃空间望远镜于1990年发射之后，已经成为天文史上最重要的仪器。它已经填补了地面观测的缺口，帮助天文学家解决了许多根本上的问题，对天文物理有更多的认识。哈勃的哈勃超深空视场是天文学家曾获得的最深入（最敏锐的）的光学影像。
exposition
What is the genre of this passage
1 The night sky has been an endless source of fascination since the start of human history. For example, the mysterious large-eyed, bronze statues of the ancient Shu Kingdom, discovered at the Chinese archeological site at Sanxingdui, were believed to have been able to look across great distances into the stars. In reality, humans can see very little of the night sky with the naked eye. And, for a long while, people were unable to understand what they could see. Not knowing what the stars were, people in ancient times used their imaginations to create a world in the sky.
1自人类历史开始以来，夜空就一直是人们着迷的源泉。例如，在三星堆中国考古遗址发现的神秘的古蜀国大眼睛青铜雕像，被认为能够远距离眺望星空。事实上，人类用肉眼几乎看不到夜空。而且，很长一段时间以来，人们都无法理解他们所能看到的东西。在不知道星星是什么的情况下，古代的人们用他们的想象力在天空中创造了一个世界。
2 Our power to investigate and thus understand space changed dramatically when the first telescope was angled at the night sky, increasing as it did the power of the human eye and enabling us to understand that the universe is far larger than was previously imaginable. The planets were seen to be worlds similar to our own, many of them even having their own moons. Soon, it was understood that the Sun was just one star among billions in the galaxy we call the Milky Way. Some 300 years later, we learnt that the Milky Way itself was just one galaxy among billions of others, spread across the blackness of space like great islands of light and matter floating in a vast cosmic ocean.
2当第一台望远镜对准夜空时，我们研究和理解太空的能力发生了巨大变化，增加了人眼的力量，使我们能够理解宇宙比以前想象的要大得多。这些行星被认为是与我们相似的世界，其中许多甚至有自己的卫星。很快，人们就明白了，太阳只是我们称之为银河系的数十亿星系中的一颗恒星。大约300年后，我们了解到银河系本身只是数十亿个星系中的一个，散布在黑暗的太空中，就像漂浮在浩瀚宇宙海洋中的光岛和物质岛。
3 Almost 400 years after the first Earth-based telescope was invented, the Hubble Space Telescope was launched into orbit, giving astronomers – indeed all of us – the first breathtakingly beautiful images of our universe taken from beyond Earth. Nothing in history has allowed us to see so much over such great distances, from enormous clouds of gas where stars are being born, to huge black holes, and even to new planets where we might conceivably find life. Not only that – it has also helped us to work out the age and nature of the universe, and discover the incredible fact that the universe is expanding at an ever-increasing speed.
3在第一台基于地球的望远镜发明近400年后，哈勃太空望远镜被发射到轨道上，为天文学家——实际上是我们所有人——提供了从地球以外拍摄的第一张令人惊叹的美丽宇宙图像。历史上没有什么能让我们在如此遥远的距离上看到如此多的东西，从恒星诞生的巨大气体云，到巨大的黑洞，甚至到我们可能发现生命的新行星。不仅如此，它还帮助我们了解了宇宙的年龄和性质，并发现了宇宙正在以不断增长的速度膨胀这一令人难以置信的事实。
4 To see even further into the universe, many countries are now engaged in building ever more advanced telescopes. Currently, China operates the world’s largest and most powerful radio telescope, the FAST telescope, completed in 2016. The 500-metre dish of the “Eye of Heaven”, as it is known, is being used in the search for dark matter, thought to be composed of subatomic particles invisible to ordinary telescopes. This vast dish also has the ability to explore regions of space billions of light years away, right at the edge of the visible universe.
4为了更深入地观察宇宙，许多国家现在都在建造越来越先进的望远镜。目前，中国运营着世界上最大、最强大的射电望远镜FAST望远镜，该望远镜于2016年完工。众所周知，“天堂之眼”的500米圆盘正被用于寻找暗物质，暗物质被认为是由普通望远镜看不见的亚原子粒子组成的。这个巨大的盘子也有能力探索数十亿光年外的太空区域，就在可见宇宙的边缘。
5哈勃望远镜和在它之后建造的太空望远镜将使我们能够看到越来越远的太空。我们将看到数十亿光年外的恒星和星系，回顾数十亿年前的过去。使用越来越大的射电望远镜作为我们的眼睛，有一天我们将能够回顾宇宙早期，即光存在之前的某个时刻。但人类对知识的追求甚至超越了这一点。宇宙中有如此多的地方尚未被探索，以至于我们仍然接近这场不可思议的探索之旅的开始。
5 The Hubble and the space telescopes constructed after it will allow us to see further and further into space. We will view stars and galaxies billions of light years away and look back at a past that was billions of years ago. Using ever-larger radio telescopes as our eyes, we will one day be able to look back to a time in the very early universe, before the existence of light. But the human quest for knowledge reaches even beyond that. So much of the universe remains unexplored that we are still close to the start of this incredible journey of discovery.
6“挑战者”号失事已经30多年了，尽管机组人员的生命不幸缩短，但他们与加加林、捷列什科娃、阿姆斯特朗和杨利伟等太空探索英雄并肩作战。这七个人的记忆将永远存在，写在星星上，激励我们与他们一起踏上人类最伟大的探索和发现之旅。挑战者号的牺牲呼唤着我们，提醒我们必须继续寻找恒星，无论它们看起来多么遥远。
6 It has now been over 30 years since the loss of Challenger and although the lives of its crew were cut tragically short, they take their place alongside the other heroes of space exploration, such as Gagarin, Tereshkova, Armstrong and Yang Liwei. The memory of those seven will live forever, written in the stars, inspiring us to join them in humanity’s greatest journey of exploration and discovery. The sacrifice of the Challenger calls to us, reminding us that we must continue to reach for the stars, no matter how distant they might seem.

What's the main idea of the passage
People will know more about the universe with the help of the large telescopes.
What did people in old times to create a world in the sky
By imaginations.
Why do you think people have always been interested in the stars
Everyone has different reasons for liking stars. Some people are simply attracted by the beauty of the starry sky, while others enjoy the romantic atmosphere of watching stars together. Some people's interest stems from curiosity about the starry sky
But if you want me to make it up for you to see, I will tell you that I like the starry sky because it is far away, unreachable, gentle, and romantic, so that they can be observed.
The more we know, the more we feel our ignorance; the more we feel how much remains unknown.
