天文学家探测到水、二氧化碳的迹象,以及外行星K2-18b的潜在生命指标。 Astronomers detect signs of water, carbon dioxide, and a potential life indicator on exoplanet K2-18b.

天文学家已经探测到K2-18b上潜在的生命迹象,K2-18b是在120光年之外的可居住区的一个外行星。 Astronomers have detected potential signs of life on K2-18b, an exoplanet in a habitable zone 120 light-years away. James Webb空间望远镜在其大气层中发现了水蒸气和二氧化碳,表明它可以支持生命。 The James Webb Space Telescope found water vapor and carbon dioxide in its atmosphere, suggesting it could support life. 硫化二甲基(DMS)这一由地球上生物体产生的化合物的暂时信号引起了人们的兴趣,尽管还需要进一步确认。 A tentative signal of dimethyl sulfide (DMS), a compound produced by living organisms on Earth, has sparked interest, though further confirmation is needed. 如果得到证实,这可能意味着在与地球截然不同的行星上存在生命,从而扩大对可居住世界的探索范围。 If confirmed, this could mean life exists on planets very different from Earth, expanding the search for habitable worlds.
