不好意思，各位！这个视频做太久了，导致更新慢了。 本视频建议全屏观看，效果更佳！ 另外，本来视频不想加字幕的，怕影响体验。但是介于本人普通话口音太重，考虑再三还是加了字幕，尴尬…… 视频章节： 00:00 宇宙有多大？ 00:32 离开地球 01:16 月球 02:10 太阳系 04:10 比邻星 04:20 半人马座alpha 04:33 银河系 06:58 本地泡 08:25 仙女座星系 09:04 本星系群 09:37 室女座超星系团 10:08 拉尼亚凯亚超星系团 11:17 巨引源 11:54 夏普利超星系团 12:13 宇宙网 13:18 宇宙空洞 14:00 暗物质和暗能量 14:56 可观测宇宙 17:42 宇宙的形态 ...

Planetary Science & Climate Change - Earth's uniqueness lies in the presence of liquid water, though not necessarily in large quantities, distinguishing it from Mars and Venus [1] - Past Mars and Venus potentially had abundant liquid water, evidenced by deuterium-to-hydrogen ratios analyzed using telescopes like the Subaru Telescope [1] - Research indicates Mars had an ocean approximately 100 meters deep around 4 billion years ago [1] - Studies using data from the ExoMars orbiter reveal short-term fluctuations in water vapor distribution on Mars, potentially impacting climate change [1] Space Exploration & Future Prospects - Astronomers are actively searching for Earth-like planets beyond our solar system, with high-precision space telescopes planned for launch in the 2040s [1] - While discovering a second Earth through spectral analysis is anticipated, immediate travel remains challenging, making Mars a primary target for human exploration [2] - The Artemis program aims to send humans to Mars, necessitating detailed climate and weather investigations [2] - Despite proposals to terraform Mars by increasing greenhouse gases, current technology faces limitations due to insufficient carbon dioxide and water resources [3] Earth's Climate & Responsibility - The Earth is facing challenges in preventing even slight increases in atmospheric temperature, leading to abnormal weather and climate change [3] - The industry emphasizes the importance of individual curiosity and interest in science and engineering to shape the future and address climate challenges [3]
