Description: TED成员及天文学家艾瑞卡·汉登带领着队伍建造了一台悬挂在巨大气球的望远镜“火球”，它飞往太空边缘，寻找恒星诞生的线索。她带我们踏上一场惊险刺激而又长达数十年的旅程，感受从望远镜从灵感到诞生的过程——并且向我们展示，当你想要突破先有知识的极限时，失败是不可避免的。

如何建造望远镜

Scientific discovery advances by looking at the universe in entirely new ways, but innovation comes with relentless setbacks. Building a balloon-borne telescope to map immense, invisible hydrogen clouds took over a decade and weathered countless failures, from destroyed sensors to a crash-landing in the desert. Even after setbacks as dramatic as a punctured balloon, the journey continues because progress grows from refusing to quit. True exploration means accepting that failure is not the end, but a vital step toward new knowledge.
