「金星は暑すぎ､火星は寒すぎ、地球はちょうどいい」と惑星科学者デイヴ・ブレインは言います。でもなぜなのでしょう？ この快いユーモアに満ちた講演でブレインは､惑星が生命を宿すための条件は何かという魅惑的な科学を探り、生命を保持する惑星の時間軸において人類はちょうどいい時にちょうどいい場所にいただけかもしれない理由を語ります。

惑星が生命を育むために必要なもの

Our planet is the only known place in the universe where 8.7 million species thrive, thanks to a rare balance of energy, nourishment, and liquid water. Even within our solar system, only Venus, Earth, and Mars once had a shot at surface water, but Earth's stable conditions set it apart. Planetary atmospheres and magnetic fields play crucial roles in protecting or stripping away the ingredients for life. With billions of potentially habitable planets in our galaxy, understanding Earth's unique story could reveal which distant worlds might also sustain life.
