摘要
在人类历史上，我们很快将首次能够运用科学方法探讨“我们是否孤独？”这一问题。系外行星发现、行星系统科学和望远镜技术的快速进展，将很快使科学家能够通过直接观测系外行星在太阳系外搜寻生命。此项工作将与在太阳系内搜寻宜居环境和生命迹象同步进行。虽然这些搜寻主题相关且会相互启发，但需采用不同的观测技术。系外行星上的生命搜寻因太阳系外待探索世界的多样性而具潜力。然而，由于对任一单独世界所获数据相对有限，也面临独特挑战。本白皮书评述科学界利用未来望远镜数据搜寻系外行星生命的能力。内容总结了“无墙系外行星生物标志研讨会”(EBWWW)的成果。EBWWW 由一系列线上与线下活动构成，有国际系外行星与天体生物学界参与，旨在评估太阳系外行星生命远程探测的科学现状与未来研究需求。
