Robin George Andrews: 金星曾经可能是一个宜居的星球，拥有液态水和海洋。然而，大约10亿年前，金星经历了失控的气候变化，导致其表面温度急剧升高，变成了如今的火山地狱。造成这种变化的原因尚不清楚，但主要嫌疑人包括年轻太阳的剧烈活动和剧烈的火山喷发。年轻太阳的剧烈活动可能导致金星上的水被蒸发，从而加剧温室效应。而大规模的火山喷发则可能释放出大量的温室气体，并破坏了金星的板块构造，从而失去了调节行星温度的能力。两种理论都有其支持的证据，但目前尚无法确定哪种理论更准确。要解决这个谜团，需要进一步的研究和探测任务。 Noah Hassenfeld: 金星的现状可能预示着地球的未来。地球和金星非常相似，但金星却变成了地狱般的存在。了解金星的演变过程，对于我们理解地球的未来至关重要。 Brian Resnick: 尽管金星表面环境恶劣，但科学家们在金星大气中探测到了磷化氢，这是一种与生命活动密切相关的物质。这引发了人们对金星上是否存在生命的猜测。如果金星云层中存在生命，那么它可能是一种适应了金星极端环境的独特生命形式，这将表明生命在宇宙中普遍存在。

Venus, once possibly habitable, is now a volcanic hellscape. The episode explores the mystery of how Venus transformed and whether Earth could face a similar fate.

Venus is the hottest, scariest planet in the solar system, but billions of years ago it may have been a lot like Earth, complete with an ocean of water. So, how did Venus go to hell? And could Earth be next?
