摘要

这是地球历史上的一个关键时刻：人类正在结束35亿至38亿年来陆地生物圈与宇宙环境相互作用的相对隔离，现在可能在地球之外留下持久的物理、化学、生物和不可预见的影响。载人任务，以及新太空时代的技术进步——比如小型化和人工智能的使用——加速了这一趋势。正在作出具有潜在深远的宇宙后果的决定。因此，迫切需要采取行动。在我们的太空探索之后可能产生的一系列影响中，有些可能通过连锁反应或指数机制导致实质性的、大规模的和/或不可逆转的变化，例如：(1)影响整个地球景观的地貌改变；(2)天体动力学变化，导致小行星撞击或轨道碎片呈指数级增长；(3)化学物质的大规模扩散，改变了某一物体上化学物质的演化和生命形式出现或演化的可能性；(4)陆地生命形式的传播，导致新的生物圈的产生或与原有生物圈的破坏/相互作用6,7；(5)地球电磁信号的变化，从而增加了被假定的地外智慧识别的可能性8,9。

期刊介绍： Nature Astronomy, the oldest science, has played a significant role in the history of Nature. Throughout the years, pioneering discoveries such as the first quasar, exoplanet, and understanding of spiral nebulae have been reported in the journal. With the introduction of Nature Astronomy, the field now receives expanded coverage, welcoming research in astronomy, astrophysics, and planetary science. The primary objective is to encourage closer collaboration among researchers in these related areas. Similar to other journals under the Nature brand, Nature Astronomy boasts a devoted team of professional editors, ensuring fairness and rigorous peer-review processes. The journal maintains high standards in copy-editing and production, ensuring timely publication and editorial independence. In addition to original research, Nature Astronomy publishes a wide range of content, including Comments, Reviews, News and Views, Features, and Correspondence. This diverse collection covers various disciplines within astronomy and includes contributions from a diverse range of voices.
