是時候重新審視這個非常古老的宇宙了。在它所有的謎團中，我們正在尋找歷史的秘密和開啟未來的鑰匙。這是一段我們如何知道怎麼研究太空的歷史。自人類首次涉足外太空以來，已經過了五十年，但如今，天空才釋出它們最大的秘密。機器人漫遊者讓我們看見火星的紅色岩石。NASA的太空探測器以超快的速度撞擊彗星。深空望遠鏡捕捉到有關恆星誕生及其坍塌成黑洞的猛烈圖像。這些都極大的改變了我們看待自己的方式。當我們自己的星球受到全球暖化效應的干擾時，我們自然而然的望向天空，想著其他的一席之地。還有其他地方可以供養生命嗎？或者，真的沒有像家一樣的地方？每集都將探討科學發現的過程，以及敢於冒險進入未知領域的科學家和探險家的迷人故事。
It's time for a new look at a very old universe. In its mysteries, we are finding the secrets of our past and the key to our future. This is a history of how we know what we do about space. Fifty years have flown by since man first ventured into outer space, but the heavens are only now yielding their greatest secrets. Robotic rovers give us eyes on the red rock of Mars. NASA probes slam into comets at hyperspeed. Deep space telescopes capture violent images of the birth of stars and their collapse into black holes. All of these have significantly changed the way we look at ourselves. As our own planet churns with the effects of global warming, it's natural to look into the heavens and wonder about the rest of the real estate. Is there anywhere else out there that can support life? Or, is there truly no place like home? Each episode will examine how the discoveries were made and the fascinating stories of the scientists and explorers who dared to venture into the uncharted territory of the universe.
