由托比·琼斯（Toby Jones）主持的科学纪录片，由英国广播公司（BBC）发行，作为2018年英国广播公司（BBC）地平线系列的一部分播放-Science Documentary hosted by Toby Jones, published by BBC broadcasted as part of BBC Horizon series in 2018- English narration

斯科特·博尔顿（Scott Bolton）在谈到太阳系中最大的木星木星时说：“要送出一艘宇宙飞船，会有一点疯狂。”?但这正是他所做的，因为斯科特（Scott）是朱诺（Juno）的负责人，这是美国国家航空航天局（NASA）的任务，旨在凝视木星旋转的云层并揭示其中的奇观。但这不是普通的世界。这部纪录片由托比·琼斯（Toby Jones）讲述，与科学家们一起进入了巨人的心脏。凯特琳·克拉特（Kaitlin Kratter）教授向我们展示了木星到底有多极端。她来到一个采石场，用最小的石头开始测量每个星球的质量。水星只有一公斤，地球只有17公斤。但是木星却完全处于另一个尺度。它是七吨，是其他所有行星总和的两倍半。就凯特琳的规模而言，这不是一堆石头，是运送他们的卡车。极端尺寸会带来极端辐射。朱诺处于美国国家航空航天局访问过的最极端环境中。通过在休斯顿的屋顶上投影一个70英尺宽的，真人大小的Juno，斯科特向我们展示了其易碎的电子产品如何用200公斤的钛包裹。正如斯科特（Scott）所说，“我们必须建造一辆装甲坦克去那里。”车队的努力是值得的。朱诺的太空气象员安德鲁·英格索尔教授透露，他们已经看到了木星内部的闪电，强度可能是地球闪电的一千倍。这可能是木星内部大量水的证据。英格索尔教授还告诉我们，大红色斑点，就像一场飓风一样，可能席卷整个地球，其下降幅度达到了他们所能看到的范围，“它可能下降了数千公里”。深入地球，事情变得越来越陌生。在加利福尼亚北部的国家点火设施中，马吕斯·米洛特博士正在使用通常用于核聚变的强大激光进行惊人的实验。他使用“给定时刻整个美国使用的功率的500倍”将氢压碎至木星内部的压力。在这些极端条件下，氢变成液态金属。朱诺正在发现木星内部有多少液态金属氢，科学家希望更好地了解这种流动的金属如何产生太阳系中最强大的极光，但木星的核心是什么？在尼斯，特里斯坦·古洛特（Tristan Guillot）教授解释了朱诺（Juno）如何利用重力绘制行星中心的图。这可以将科学家带回到太阳系的最早年代，因为木星是最古老的行星，它应该包含有关其自身创造的线索。通过画出木星的轮廓，特里斯坦发现了一个巨大的岩石核-可能是地球质量的十倍。现在人们认为木星起初是一个小的岩石世界。但是令人惊讶的是，因为朱诺的发现表明这个核心可能是“模糊的”。特里斯坦（Tristan）认为这颗行星遭到了类似于流星的轰炸。正如他所说，“木星与我们所想的完全不同”。特里斯坦（Tristan）认为这颗行星遭到了类似于流星的轰炸。正如他所说，“木星与我们所想的完全不同”。特里斯坦（Tristan）认为这颗行星遭到了类似于流星的轰炸。正如他所说，“木星与我们所想的完全不同”。'To send a spacecraft there is a little bit insane,' says Scott Bolton when talking about Jupiter, the largest planet in the solar system. But that is exactly what he has done, because Scott is head of Juno, the Nasa mission designed to peer through Jupiter's swirling clouds and reveal the wonders within. But this is no ordinary world. This documentary, narrated by Toby Jones, journeys with the scientists into the heart of a giant.Professor Kaitlin Kratter shows us how extreme Jupiter is. She has come to a quarry to measure out each planet's mass with rocks, starting with the smallest. Mercury is a single kilogram, and the Earth is 17. But Jupiter is on another scale entirely. It is seven tonnes - that is two and a half times the mass of all the other planets combined. On Kaitlin's scale it is not a pile of rocks, it is the truck delivering them. With extreme size comes extreme radiation. Juno is in the most extreme environment Nasa has visited. By projecting a 70-foot-wide, life-size Juno on a Houston rooftop, Scott shows us how its fragile electronics are encased in 200kg of titanium. As Scott puts it, 'we had to build an armoured tank to go there.'The team's efforts have been worthwhile. Professor Andrew Ingersoll, Juno's space weatherman, reveals they have seen lightning inside Jupiter, perhaps a thousand times more powerful than Earth's lightning. This might be evidence for huge quantities of water inside Jupiter. Prof Ingersoll also tells us that the Great Red Spot, a vast hurricane-like storm that could swallow the Earth whole, goes down as far as they can see - 'it could go down 1,000s of kilometres'.Deeper into the planet and things get stranger still. At the National Ignition facility in northern California, Dr Marius Millot is using powerful lasers normally used for nuclear fusion for an astonishing experiment. He uses '500 times the power that is used for the entire United States at a given moment' to crush hydrogen to the pressures inside Jupiter. Under these extreme conditions, hydrogen becomes a liquid metal. Juno is finding out how much liquid metallic hydrogen is inside Jupiter, and scientists hope to better understand how this flowing metal produces the most powerful aurora in the Solar System.But what is at Jupiter's heart? In Nice, Prof Tristan Guillot explains how Juno uses gravity to map the planet's centre. This can take scientists back to the earliest days of the solar system, because Jupiter is the oldest planet and it should contain clues to its own creation. By chalking out an outline of the Jupiter, Tristan reveals there is a huge rocky core - perhaps ten times the mass of Earth. It is now thought Jupiter started as a small rocky world. But there is a surprise, because Juno's findings suggest this core might be 'fuzzy'. Tristan thinks the planet was bombarded with something akin to shooting stars. As he puts it, 'Jupiter is quite unlike we thought'.
