永久冻土和冰是低温行星和其他天体的重要组成部分，在宇宙中非常丰富。地球是许多冷型行星之一。地球的永冻层和冰提供了一个机会来测试假设，这些假设可以应用于在地外低温行星上寻找可能的生态系统和潜在的生命。极地和高山地区的冻土沉积物是自然生态系统，具有低温保存生物物质及其遗传信息的独特功能。因此，永久冻土研究可以重建发生在新生代的事件，并预测在人为因素对这些生态系统产生影响之前可能保存下来的可能生命，并且可以在其他低温行星的冰或永久冻土中找到。
Permafrost and ice are important components of cryogenic planets and other bodies, which are abundant in the universe. Earth is one of many planets of the cold type. Earth's permafrost and ice provide an opportunity to test hypotheses that could be applied in the search for possible ecosystems and potential life on extraterrestrial cryogenic planets. Permafrost sediments in polar and alpine regions are natural ecosystems with a unique feature of low‐temperature preservation of the biological material and its genetic information. Therefore, permafrost studies allow reconstruction of the events that occurred in the Cenozoic and the prediction of possible life that might have been preserved before the effect of anthropogenic factors on these ecosystems, and could be found within ice or permafrost on other cryogenic planets.
