Hundred of tons of space debris, most of it microscopic size particles, falls to earth every single day. But a fireball the size of a football foeld could land here too. An impact 65 million years ago appears to have ended the reign of the dinosaurs. Now the idea that our planet orbits a shooting gallery of comets and asteroids is getting serious attention. Join scientists investigating how comets and asteroids may have been reshaping evolution. 天下掉下馅饼或是奇迹，但实际上我们的地球每天都有数以百吨的太空残骸掉落下来，这些残骸大多数小到难以察觉，只是用显微镜才能看的清楚，只有用显微镜才可以看得清楚，但有的也有像足球场那么大。早在6千5百万年前，太空中火球的掉落被宣告了恐龙统治时期的结束。本节目将介绍这些太空火球在地球上存在的各种奇特形态，看看这些虽然微乎其微、但同时也是在摧残地球的潜在杀手是怎样影响生态环境的。此外，我们要到外太空寻找致命的彗星与小行星，意外的发现有可能是我们避开火球灾难，甚至解开地球生命起源的秘密。
