あらすじ・解説
Planet Earth, starting with the Solar Nebula and a supernova explosion. It explains the accretion process, where dust particles collided and coalesced to form planetesimals and eventually protoplanets, including Earth. The transcript then describes the Hadean Eon, a period of intense collisions that created Earth's initial lava state and delivered water. Finally, it covers the differentiation of Earth's layers, the formation of the Moon via a giant impact, and the conditions necessary for life to emerge, emphasizing the unique circumstances that made Earth habitable.
