本片通过最新的科技信息和最强大的CGI技术，探索宇宙的终极秘密，让你认识到一个真实的宇宙。共6集。 　　Extreme Universe 　　In the Extreme Universe, there are realms of such extremes, we barely know them. But we're beginning to venture into places we never thought we'd reach. And the most profound mysteries of science are coming into view. The Extreme Universe gives vital insights into a world we thought we knew, using an unprecedented combination of the most current scientific information, mind-blowing CGI and relevant comparisons and analogies. The night sky is a fascinating spectacle, but for ancient civilisations it was the key to their survival. Over thousands of years, there have been a lot of scientific discoveries, but it was our ancestors' first observations of the cosmos that put us on the path to modern civilisation which led to some of mankind s greatest creations. Are we alone in the vast expanse of the universe? It's a question people have been asking for thousands of years and we're closer than ever to finding the answers. We'll travel deep into the cosmos to witness the most violent impacts in the universe and take you into the heart of the universe's biggest space-storms - weather like 11,000-mile-per-hour winds or storms of raining liquid methane. Planets, moons, and stars are all at risk of violent upheaval. The violence unleashed on these worlds provides a frightening blueprint of what could happen closer to home. No matter how we try, there's no way to prepare for nature s cosmic fury 　　Part 1: Is Anyone Out There 　　Travel to the farthest reaches of the universe, as this exploratory space documentary series asks 'is anyone out there'? 　　Part 2: Collision Course 　　WARNING, this episode contains flashing images which may cause Photo Sensitive Epilepsy. Witness some of the most violent impacts in the universe, and meet the people protecting us from the fallout of these cosmic collisions. 　　Part 3: Space Storms 　　Witness the relentless power of Earth's worst weather, before travelling the universe to find the 17,500kmh winds and methane storms of space. 　　Part 4: Edge of Space 　　Delve into the unknown on a journey into deep oceans and deep space, as we seek the answers to some of mankind's most unfathomable questions. 　　Part 5: Time Bombs 　　Planets, moons and stars can all face violent upheaval at any moment. Is it possible to predict when Mother Nature will strike? 　　Part 6: Star Gates 　　Throughout history, humans have been fascinated by the stars. Discover how astronomy played a crucial role in early civilisations.

北极狼群荒野生活的亲密纪录 　　加拿大的埃尔斯米尔岛，距离北极不到五百哩。在这酷寒的极地，只有极特殊的动物才能生存，白狼就是其中之一。在世上其他地区，狼群饱受人类的迫害而对人类深怀戒心，难以靠近观察。然而此地人迹罕至，白狼徜徉在冰冷荒原上悠然自得，对人类毫不畏惧。国家地理摄影师吉姆．布兰登勃格与研究狼群三十年的生物学家戴夫．米奇连袂前往此岛，在极为恶劣的环境下，拍摄了有史以来对狼群观察最细致、最亲密的生态纪录片

黑洞其实也是个星球,只不过它的密度极大, 靠近它的物体都被它的引力所约束(就好像人在地球上没有飞走一样)。对于地球来说，以第二宇宙速度来飞行就可以逃离地球，但是对于黑洞来说，它的第二宇宙速度之大，竟然超越了光速，所以连光都跑不出来，于是射进去的光没有反射回来，我们的眼睛就看不到任何东西，只是黑色一片。一些科学家认为光的速度比黑洞慢，所以被吸进去，当速度比黑洞快时就可以穿过黑洞边缘。
