BBC纪录片《超级望远镜：前往宇宙边际的任务 Super Telescope: Mission to the Edge of the Universe 2022》全1集 英语外挂中英双字 1080P超清下载
随着美国宇航局发布詹姆斯·韦伯太空望远镜的第一批图像，这部电影讲述了望远镜建造的内幕以及天文学家拍摄的第一张遥远恒星和星系的照片。它会是我们宇宙有史以来拍摄的最深的图像吗？詹姆斯·韦伯望远镜是哈勃的继任者，比哈勃望远镜强大100倍，是有史以来技术最先进的望远镜。它将比哈勃更早地追溯到宇宙大爆炸后大约2亿年的时代，那时第一批恒星和星系出现了。韦伯的主要任务是捕捉我们可见宇宙边缘这些物体发出的微弱光线，以便科学家能够了解它们是如何形成的，但它的仪器非常敏感，它也可能是第一台探测遥远星球上生命迹象的望远镜。詹姆斯·韦伯望远镜是对其工程团队技能的80亿英镑赌博。这是第一台设计用于在太空展开的望远镜——这是一个复杂的两周操作，其中178个释放装置必须全部工作——其中107个仅在望远镜的遮阳板上。如果只有一个失败，昂贵的望远镜可能会成为一个巨大的太空垃圾。从20世纪80年代末的构想开始，韦伯的建造就面临着巨大的技术挑战。该团队必须建造一个比哈勃望远镜大六倍的镜子，并建造一个网球场大小的巨大遮阳板，将它们折叠起来，以便它们能够装入阿丽亚娜5号火箭，然后找到一种方法在太空中展开它们。这部电影用建造詹姆斯·韦伯太空望远镜的工程师和将要使用它的天文学家的话讲述了这部望远镜的内幕。As Nasa releases the first images from the James Webb Space Telescope, this film tells the inside story of the telescope's construction and the astronomers taking its first picture of distant stars and galaxies. Will it be the deepest image of our universe ever taken? The successor to Hubble, and 100 times more powerful, the James Webb is the most technically advanced telescope ever built. It will look further back in time than Hubble to an era around 200 million years after the Big Bang, when the first stars and galaxies appeared. Webb's primary mission is to capture the faint light from these objects on the edge of our visible universe so that scientists can learn how they formed, but its instruments are so sensitive it could also be the first telescope to detect signs of life on a distant planet. The James Webb Telescope is an ￡8 billion gamble on the skills of its engineering team. It’s the first telescope designed to unfold in space – a complicated two-week operation in which 178 release devices must all work - 107 of them on the telescope's sun shield alone. If just one fails, the expensive telescope could become a giant piece of space junk. From its conception in the late 1980s, the construction of Webb has posed a huge technical challenge. The team must build a mirror six times larger than Hubble’s and construct a vast sun shield the size of a tennis court, fold them up so they fit into an Ariane 5 rocket, then find a way to unfold them in space. This film tells the inside story of the James Webb Space Telescope in the words of the engineers who built it and the astronomers who will use it.
