论文摘要
在第一个星系形成后，宇宙微波背景（CMB）的温度等于土星的月球泰坦（Saturn）月球泰坦（Saturn Moon Titan）的表面温度为94k，在红移Z = 33.5处。泰坦式物体将保持这种表面温度的成绩，而不论它们与恒星的距离如何。泰坦具有在其地下水上海洋中熟悉的生活的潜力，以及液态甲烷和乙烷在其表面上的河流，湖泊和海洋中的新形式。未来对泰坦的生命的潜在发现将使最早的生命形式在宇宙中最早的星系的金属丰富环境中出现，这只是大爆炸之后的100 Myr。
The temperature of the cosmic microwave background (CMB) was equal to the surface temperature of Saturn's moon Titan, 94K, at a redshift z=33.5, after the first galaxies formed. Titan-like objects would have maintained this surface temperature for tens of Myr irrespective of their distance from a star. Titan has the potential for the chemistry of familiar life in its subsurface water ocean, as well new forms of life in the rivers, lakes and seas of liquid methane and ethane on its surface. The potential future discovery of life on Titan would open the possibility that the earliest lifeforms emerged in metal-rich environments of the earliest galaxies in the universe, merely 100 Myr after the Big Bang.
