美国宇航局预测地球将在10亿年内失去氧气, 因为太阳的亮度会增加, 使它无法居住. NASA predicts Earth will lose oxygen in one billion years as the Sun brightens, making it uninhabitable.

美国宇航局支持的研究预测,地球富含氧气的大气层将在10亿年内消失,因为太阳的亮度逐渐减弱,使得这个星球无法适应复杂生命. NASA-backed research predicts Earth's oxygen-rich atmosphere will vanish in about one billion years due to the Sun's gradual brightening, making the planet uninhabitable for complex life. 这一时间表比之前的估计要早得多, 并且强调地球可居住窗口是有限的, 不管人类造成的威胁如何. This timeline is significantly sooner than previous estimates and highlights that Earth's habitable window is finite regardless of human-made threats.
