宇宙一直存在吗？它如何变成一个可以容纳生命的地方？我们星球的诞生是什么样的？是我们一个人，还是有等待发现的外星世界？NOVA在“起源”（Origins）中提出了一些惊人的新答案，这是一部由四部分组成的NOVA微型系列，由美国自然历史博物馆海顿天文馆馆长动态天体物理学家尼尔·德格拉斯·泰森主持。泰森（Tyson）带领观众踏上宇宙之旅，探索时间的起点并到达遥远的宇宙，寻找生命的初次搅动及其在其他世界上的踪迹。[编辑]地球诞生48分01秒该系列的第一个小时，“起源：地球是出生”，使观众可以窥见地球动荡的前10亿年，这是持续不断的灾难时期。生动的动画让观看者亲眼目睹了地球与被认为是火星大小的物体之间发生泰坦尼克号碰撞而造成的创伤性月亮诞生。早期的地球在流星和彗星的轰击下，在大规模的火山喷发中摇摇欲坠，并在酸雨热中洗刷，这似乎是生命扎根的极不可能的地方。尽管有如此猛烈的开端，科学家们发现了新的线索，认为赋予生命的水和氧气比我们以前认为的要早得多。[编辑]生命如何开始48m36s第二个小时，“起源：生命如何开始”，零星地揭开了人类的神秘面纱。到底是怎么回事。加入寻找在最不可能发生的地方繁殖的强壮微生物的探索：地下两英里处的矿井里的岩石内，洞穴中滴入的酸与汽车电池一样强，以及从太平洋海底喷出的有害气泡。这些坚韧微生物的生存表明它们可能与地球上最初的原始生命形式有关。泰森通过调查在世界各地发现的30亿年前的岩石和陨石中诱人的和有争议的化学“特征”，加深了搜索的范围。[编辑]??外国人在哪里？49m40s在第三个小时中，“起源：外国人在哪里？”，泰森探讨了一些挑衅性的问题，例如：“ ET”会像我们还是科幻小说中的生物？在我们地球上那些聪明才智与我们自己截然不同的聪明动物中已经存在“异形”吗？生命可以在我们的宇宙中稀少或普遍存在的行星吗？[编辑]回到开始49分44秒小时四以爆炸声开头：一切开始的爆炸声。“起源：回到起点”探讨了早期宇宙的巨大，令人难以置信的力量如何使可居住世界出现。线索始于科学家之间的竞赛，他们从深空的微波“窃窃私语”中捕捉到了大爆炸的残酷回响。这场比赛使安德斯高空的劣等天文学家托尼·雷德黑德（Tony Readhead）和他的简易探测器与美国宇航局的科学家和他们最新的卫星探测器相撞。随着大爆炸回声的计算机动画出现在屏幕上，泰森与观众分享了他的兴奋。它离原始宇宙的“照片”很近。在这里，我们瞥见了所有星系，恒星和行星最终从其生长的种子。Has the universe always existed? How did it become a place that could harbor life? What was the birth of our planet like? Are we alone, or are there alien worlds waiting to be discovered? NOVA presents some startling new answers in "Origins," a groundbreaking four-part NOVA miniseries hosted by dynamic astrophysicist Neil deGrasse Tyson, Director of the Hayden Planetarium at the American Museum of Natural History. Tyson leads viewers on a cosmic journey to the beginning of time and into the distant reaches of the universe, searching for life's first stirrings and its traces on other worlds.[edit] Earth is Born 48m01sThe series' first hour, "Origins: Earth is Born," gives viewers a spectacular glimpse of the tumultuous first billion years of Planet Earth'a time of continuous catastrophe. Vivid animation lets viewers witness the traumatic birth of the moon from a titanic collision between Earth and an object believed to have been the size of Mars. Bombarded by meteors and comets, rocked by massive volcanic eruptions, and scoured by hot acid rain, the early Earth seems a highly improbable place for life to have taken root. Despite such violent beginnings, scientists have found new clues that life-giving water and oxygen appeared on our planet much earlier than previously thought.[edit] How Life Began 48m36sHour Two, "Origins: How Life Began," zeroes in on the mystery of exactly how it happened. Join the hunt for hardy microbes that flourish in the most unlikely places: inside rocks in a mine shaft two miles down, inside a cave dripping with acid as strong as a car battery's, and in noxious gas bubbles erupting from the Pacific ocean floor. The survival of these tough microorganisms suggests they may be related to the planet's first primitive life forms. Tyson deepens the search by investigating tantalizing and controversial chemical "signatures" of life inside three-billion-year-old rocks and meteorites found around the world.[edit] Where are the Aliens?49m40sIn Hour Three, "Origins: Where are the Aliens?," Tyson explores such provocative questions as: would "ETs" resemble us or the creatures of science fiction? Are there "aliens" already amongst us on Planet Earth's brainy creatures whose intelligence is very different from our own? And are planets on which life can flourish rare or common in our universe?[edit] Back to the Beginning49m44sHour Four starts with a bang: the big bang in which everything began. "Origins: Back to the Beginning" explores how the colossal, mind-boggling forces of the early universe made it possible for habitable worlds to emerge. The clues begin with a race among scientists to capture lingering echoes of the big bang's ferocious energy in a microwave "whisper" from deep space. The race pits underdog astronomer Tony Readhead and his improvised detector in the high Andes against NASA scientists and their state-of-the-art satellite probe. Tyson shares his excitement with viewers as computer animation of the big bang's echo emerges on the screen. It's as close as we can get to a "photograph" of the primordial universe. Here we glimpse the seeds from which all the galaxies, stars, and planets eventually grew.
