Understanding the Universe - An Introduction to Astronomy, 2nd Edition - Series 1 - Part 2

一般信息：
2007年The Teaching Company出版的Alex Filippenko主持的科学纪录片-英文旁白

信息
Understanding the Universe: An Introduction to Astronomy, 2nd Edition 是对这张照片今天所处位置的非技术描述。在 96 个插图丰富的半小时讲座中，您将深入探讨天文学的主要概念、方法和发现，从古人绘制的星座，到太阳系行星探测器的最新报告，到最探测时空最远边界的望远镜提供的最新图像。
这些讲座全面更新了 Alex Filippenko 教授 1998 年版的本课程及其 2003 年的配套课程。本课程中的所有材料都是集成的，因此在您开发允许您探索宇宙的概念工具时，一个主题建立在另一个主题之上。例如，对太阳系的研究自然会导致对其他恒星周围行星的研究以及宇宙其他地方存在生命的可能性。同样，彩虹和类似的大气现象引入了光的主题，而光是解开恒星和星系之谜的钥匙。
Filippenko 博士使用了数千张图表和照片。有将近 300 部短片和计算机动画可以让天文现象更容易理解，并且当您放大宇宙时，它们将行星、恒星和星系置于背景中。作为课堂表演者，Filippenko 博士喜欢使用网球、苹果、纸盘和其他物体来解释科学概念的简单、易于重现的演示。此外，他还有类比的天赋：有一次，他将一个尔格的能量含量比作一只苍蝇做一个俯卧撑，从而使它的能量含量变得生动！
总而言之，本课程是体验全年大学天文学入门课程的绝佳机会，该课程由五次获得加州大学伯克利分校“最佳教授”称号的教授授课，他本人是一些研究的主要参与者在 th 的突破性发现e 领域的前沿。 Filippenko 教授既是世界一流的教师又是研究人员：2006 年，他被卡内基教学促进基金会评为四位年度全国教授之一，1998 年，他的国际天文学家团队获得了顶级“科学奖”年度突破”，以表彰他们惊人的发现，即宇宙正在加速膨胀——这一发现正在动摇物理学的基础。
观察天堂
21. 星星的颜色
恒星的表面温度决定了它的表观颜色。最热的恒星呈蓝色，最冷的恒星呈红色；中等温度下的恒星呈白色。太阳是一颗白色的星星。
22. 原子指纹
在原子中不同能级之间跳跃的电子以每种元素特有的方式发射和吸收光子。因此，天文学家可以利用远处物体发出的光来推断它们的化学成分。
23.现代望远镜
吨今天的望远镜旨在以相对较低的成本提供巨大的聚光镜。这些镜子将来自远处物体的光线聚焦到灵敏的电子探测器上，这些探测器的效率远高于传统的摄影胶片。
24. 更好的眼睛
本讲座着眼于射电望远镜、地面红外望远镜的自适应光学系统以及 NASA 的大型天文台，其中包括哈勃太空望远镜、钱德拉 X 射线天文台和斯皮策太空望远镜。
25. 我们的太阳，最近的恒星
在开始一系列关于太阳系的讲座时，您将从太阳开始，从内部探索到表面。太阳黑子是与强磁场相关的较冷区域，剧烈的喷发将太阳物质吹向太空。
26. 地球，从太阳算起的第三块岩石
地球是四颗最靠内的行星或类地行星之一。其他的是水星、金星和火星。所有这些都相对较小，多岩石且致密。这个讲座考察了地球的结构，pr特性，以及影响它的力量。
27. 我们的月球，地球最近的邻居
本次讲座涵盖了有关月球的丰富知识，月球是一个坑坑洼洼的世界，在面向地球的一侧有大量充满熔岩的盆地，但在月球的背面却很少有这样的特征——月球并不是永远黑暗的。
28.水星和金星
水星和金星虽然与地球大体相似，但在细节上有所不同。水星的大气层可以忽略不计，而且有很多陨石坑。金星拥有令人难以置信的厚大气层，并遭受极端的温室效应，使其非常热。
29. 火星和火星人
最近的火星任务提供了早期富水时代可能孕育了原始生命的证据。今天，火星是一个寒冷的、显然没有生命的世界。火星陨石中存在化石生命的证据仍然存在争议。
30. 木星及其惊人的卫星
火星之外是四颗气态巨行星：木星、土星、天王星和海王星。木星是太阳系迄今为止最大的行星。它的卫星在Clude Io 是火山活跃的，而 Europa 在其冰冻表面下可能有液态水海洋。
31. 壮丽的土星
土星以其广泛的环系统而闻名，最近由于卡西尼号宇宙飞船而成为人们关注的焦点，该探测器在土星最大的卫星土卫六上进行了探测；并且还发现了月球土卫二上存在液态水的证据。
32.天王星和海王星，小巨人
尽管天王星和海王星的质量不如木星和土星，但它们的相似之处在于它们主要由氢和氦组成。两者都有奇异的磁场，这些磁场相对于行星的旋转轴高度倾斜并偏离行星的中心。

纪录片内容简介：

General Information：
Science Documentary hosted by Alex Filippenko, published by The Teaching Company in 2007- English narration

Information
Understanding the Universe: An Introduction to Astronomy, 2nd Edition is a nontechnical description of where that picture stands today. In 96 richly illustrated half-hour lectures, you will survey the main concepts, methods, and discoveries in astronomy - in-depth - from the constellations drawn by the ancients, to the latest reports from planetary probes in the Solar System, to the most recent images offered by telescopes probing the farthest frontiers of space and time.
These lectures fully update Professor Alex Filippenko's 1998 edition of this course and his companion course from 2003. All of the material in this course is integrated so that one topic builds on another as you develop the conceptual tools that allow you to explore the Universe. For example, the study of the Solar System leads naturally to the investigation of planets around other stars and the possibility of life elsewhere in the cosmos. Likewise, rainbows and similar atmospheric phenomena introduce the subject of light, and light is the key to unraveling the mysteries of stars and galaxies.
Dr. Filippenko uses thousands of diagrams and photographs. There are almost 300 short movies and computer animations that make astronomical phenomena easier to understand, and they put planets, stars, and galaxies into context as you zoom through the cosmos. A showman in the classroom, Dr. Filippenko delights in simple, easily reproducible demonstrations that use tennis balls, apples, paper plates, and other objects to explain scientific concepts. Furthermore, he has a gift for analogies: at one point, he makes the energy content of one erg vivid by comparing it to one fly doing one push-up!
Altogether, this course is an unrivalled opportunity to experience a full-year introductory college course on astronomy, delivered by a five-time winner of "Best Professor" on campus at the University of California, Berkeley, who himself is a leading participant in some of the groundbreaking discoveries at the forefront of the field. Professor Filippenko is both a world-class teacher and researcher: In 2006 he was named one of four national Professors of the Year by The Carnegie Foundation for the Advancement of Teaching, and in 1998 his international team of astronomers was credited with the top "science breakthrough of the year" for their amazing discovery that the expansion of the Universe is speeding up - a finding that is now shaking the foundations of physics.
Observing the Heavens
21. The Colors of Stars
The surface temperature of a star determines its apparent color. The hottest stars are bluish in color, and the coldest stars are reddish; stars at intermediate temperatures appear white. The Sun is a white star.
22. The Fingerprints of Atoms
Electrons jumping between different energy levels in atoms emit and absorb photons in a characteristic way for each element. Thus, astronomers can use the light from distant objects to deduce their chemical compositions.
23. Modern Telescopes
Today's telescopes are designed to provide huge light-gathering mirrors at relatively low cost. The mirrors focus light from distant objects onto sensitive electronic detectors that are far more efficient than traditional photographic film.
24. A Better Set of Eyes
This lecture looks at radio telescopes, adaptive optics for ground-based infrared telescopes, and NASA's Great Observatories, which include the Hubble Space Telescope, Chandra X-Ray Observatory, and Spitzer Space Telescope.
25. Our Sun, the Nearest Star
Beginning a sequence of lectures on the Solar System, you start with the Sun, which you explore from the interior to the surface. Sunspots are cooler regions associated with strong magnetic fields, and violent eruptions blast solar material into space.
26. The Earth, Third Rock from the Sun
Earth is one of the four innermost, or terrestrial, planets; the others are Mercury, Venus, and Mars. All are relatively small, rocky, and dense. This lecture examines Earth's structure, properties, and the forces that affect it.
27. Our Moon, Earth's Nearest Neighbor
This lecture covers the wealth of knowledge about the Moon, a heavily cratered world with extensive lava-filled basins on the Earth-facing side and yet few such features on the far side—which is not perpetually dark.
28. Mercury and Venus
Though broadly similar to Earth, Mercury and Venus differ in detail. Mercury has a negligible atmosphere and is heavily cratered. Venus has an incredibly thick atmosphere and suffers from an extreme greenhouse effect that makes it intensely hot.
29. Of Mars and Martians
Recent missions to Mars provide evidence for an early water-rich era that may have fostered primitive life. Today, Mars is a cold, apparently lifeless world. Evidence for fossil life in a Martian meteorite remains controversial.
30. Jupiter and Its Amazing Moons
Beyond Mars lie the four gas giants: Jupiter, Saturn, Uranus, and Neptune. Jupiter is the Solar System's largest planet by far. Its moons include Io, which is volcanically active, and Europa, which may have an ocean of liquid water below its frozen surface.
31. Magnificent Saturn
Best known for its extensive ring system, Saturn has come into focus recently thanks to the Cassini spacecraft, which landed a probe on Saturn's largest moon, Titan; and also discovered evidence of liquid water on the moon Enceladus.
32. Uranus and Neptune, the Small Giants
Though less massive than Jupiter and Saturn, Uranus and Neptune are similar in that they consist mostly of hydrogen and helium. Both have bizarre magnetic fields that are highly tilted relative to the planet's rotation axis and offset from the planet's center.
