韋伯太空望遠鏡
NASA去年公佈了來自占士·韋伯太空望遠鏡的首輯圖像，堪稱史上最深遠的宇宙圖片，令人嘆為觀止。此作記錄了韋伯的建造過程，並採訪了一眾負責拍攝遙遠恆星及星系的天文學家，讓觀眾進一步了解韋伯背後的科技和挑戰。
占士·韋伯太空望遠鏡是哈勃太空望遠鏡的後繼者，性能比後者高百倍，為當今世上最先進頂尖的望遠鏡。它將超越哈勃，回溯至更遠古的宇宙，一探大爆炸後２億年的風光，見證首批恆星及星系的誕生。韋伯的主要任務是捕捉可觀測宇宙邊際的天體所發出的微弱星光，讓科學家能了解它們的形成。韋伯配備的儀器敏感度極高，任務過程中也許甚至能成為首個探測到系外行星生命體的望遠鏡。
As NASA releases the first images from the James Webb Space Telescope, this BBC Horizon 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 a hundred 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 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.
