The car has shrunk the world, increased personal freedom and in so many ways expanded our horizons, but there is a flipside. Fumes from car exhausts have helped to destroy our environment, poisoned the air we breathe and killed us in far more straightforward ways. But all that is going to change. 　　This episode enters a world where cars can drive themselves, a world where we are ...

Horizon is an ongoing and long-running British documentary television series on BBC that covers science and philosophy.

由眾多科學(xué)家和工程師研發(fā)接近30年的“卡西尼號(hào)”太空探測(cè)器在經(jīng)過長(zhǎng)達(dá)近7年的漫長(zhǎng)太空旅行之后，順利進(jìn)入環(huán)繞土星轉(zhuǎn)動(dòng)的軌道，開始對(duì)土星大氣、光環(huán)和衛(wèi)星進(jìn)行歷時(shí)4年的科學(xué)考察。卡西尼號(hào)”還攜帶了探測(cè)土星最大衛(wèi)星土衛(wèi)六的探測(cè)器，取名為“惠更斯號(hào)”。在探測(cè)任務(wù)20年后，卡西尼號(hào)土星探測(cè)器燃料將盡，科學(xué)家控制其向土星墜毀，在此之后，卡西尼號(hào)與地球失去聯(lián)系，它進(jìn)入土星大氣層燃燒成為土星的一部分。在卡西尼號(hào)毀滅的最后一秒鐘，它都堅(jiān)守使命，往地球傳輸數(shù)據(jù)，最后才壯烈沖向大氣層。

BBC氣象員彼得?吉布斯沖動(dòng)地回到了他曾經(jīng)生活和工作過的英國(guó)南極調(diào)查局哈雷研究站。當(dāng)時(shí)，哈雷研究站在臭氧空洞的發(fā)現(xiàn)中起到了重要作用，而今天，它仍然在諸多領(lǐng)域作出了許多重要的發(fā)現(xiàn)，例如：人類生活如何受到太陽活動(dòng)的影響、星際旅行研究、以及人類導(dǎo)致的氣候變化所產(chǎn)生的威脅等。彼得此行還肩負(fù)著救援的使命，由于冰山移動(dòng)，哈雷研究站可能會(huì)隨著巨大的冰山飄向遠(yuǎn)方。

水是生命之源，科學(xué)家用望遠(yuǎn)鏡和探測(cè)器尋找地球之外的水源，從地球環(huán)境模擬生態(tài)演變，發(fā)現(xiàn)太陽系的多顆行星和衛(wèi)星都有汪洋跡象，并可能有生命存活至今。我們苦苦尋找的外星生命，也許就近在身邊，這結(jié)論挺叫人興奮的。

This is the story of how our solar system will be transformed by the aging sun before coming to a spectacular end in about eight billion years. Astronomers can peer into the far future to predict how it will happen by analysing distant galaxies, stars and even planets in their final moments. 　　In this film, Horizon brings these predictions to life in a peaceful midwestern town th...
