**课程名称：** 小绿人：寻找地外生命 (Little Green Men: The Search for Life Beyond Earth) **课程概述：** 本课程旨在深入探讨人类在探索“我们是否孤独？”这一古老命题的过程中所采取的步骤。我们将研究人类如何在无意中向宇宙宣告自身的存在，以及如何主动发送有目的性的信号。课程还将剖析远距离通讯所面临的挑战，回顾那些曾被误认为接触外星生命的“虚假警报”，并探讨外星生命需要具备哪些条件才能在其他星球上生存。此外，我们还将学习地球上的生命形态（尤其是极端微生物）如何为我们理解其他星球上的生命提供启示。 **课程包含的额外精彩内容：** * **什么是天文学？** (What on Earth is Astronomy?) * **迷你课程：日食** (Mini-Lesson: Eclipses) * **迷你课程：流星雨** (Mini-Lesson: Meteor Showers) * **迷你课程：极光** (Mini-Lesson: Aurora) * **阿尔忒弥斯计划：美国重返月球** (Project Artemis: America Returns to the Moon) **课程主题（核心内容）：** 1. **目标设定** 2. **热身活动** 3. **“我们是否孤独？”这一问题的意义** 4. **历史上的文明互动范例** 5. **生命的定义及其重要性** 6. **微生物生命与高级生命** 7. **地外生命存在的可能性** 8. **远距离探测生命的方法** 9. **从金星的污染现象中获得的启示** 10. **我们太阳系内生命存在的可能性** 11. **公众对火星生命的迷恋** 12. **火星运河与冰盖的传说** 13. **德雷克公式（Drake Equation）** 14. **搜寻地外文明计划（SETI）** 15. **宜居带（Habitable Zones）** 16. **离开太阳系的探测器：旅行者1、2号，先驱者10、11号** 17. **向外星人发送信息** 18. **地球上的极端微生物及其对地外生命研究的启示** 19. **哈达尔带（Hadal Zone）** 20. **系外行星（Exoplanets）** 21. **地球向太空的无线电和电视广播** 22. **信号强度与距离** 23. **虚假警报与脉冲星** 24. **通讯挑战：共同语言与距离** 25. **发现地外生命的潜在影响** 26. **测试题** 27. **跨学科活动** **课程大纲：** 无
The age-old question, "Are we alone?" This lesson explores the steps humanity has taken to try and answer that question. How have we inadvertently signaled to the universe that we are here and how have we tried to send purposeful signals? What are some of the difficulties we face in trying to communicate over great distances? Have we had false alarms thinking that we had contacted life on other planets? What would life on other planets have to be like to survive there? Can life that exists on Earth tell us anything about life that might exist on other planets?This Course includes great BONUS LESSONS:What on Earth is Astronomy?Mini-Lesson: EclipsesMini-Lesson: Meteor ShowersMini-Lesson: AuroraProject Artemis: America Returns to the MoonLittle Green Men - the Search for Life Beyond Earth1.
