南极光 “哈雷六号”科考站上空的南极光 为了庆祝南极洲日，你可以在哈雷六号上看到南极光的耀眼光芒，哈雷六号是英国南极地区哈雷研究站60年历史的最新版本。该模块化建筑位于液压腿上，可通过可伸缩的滑雪板移动。先前的五个设施，哈雷I-V，都因南极洲恶劣的气候而受损，并被退役。自2017年以来，当科学家们监测周围首当其冲的冰架上的危险裂缝时，哈雷在南极黑暗的冬季无人值守，但研究小组为它配备了一个自动微型涡轮，当雪堆堆积起来时，它的大气仪器仍在滴答作响。第一个南极日是1959年12月1日12个国家和平同意签署南极条约，将地球最南端的大陆奉献给追求科学的事业。这项协议是美国和苏联在冷战加速期间通过的，60年后成为全球关系的一个重要里程碑，已经扩大到包括54个国家。

In honor of Antarctica Day, you're seeing the southern lights dazzle above Halley VI, the latest version of the six-decade-old Halley Research Station in the British Antarctic Territory. The modular building stands on hydraulic legs and is movable via retractable skis. The five previous facilities, Halley I–V, were each compromised by Antarctica's harsh climate and were decommissioned. Since 2017, while scientists monitor dangerous cracks in the surrounding Brunt Ice Shelf, Halley has been unmanned during the dark Antarctic winter months—but the research team equipped it with an autonomous micro-turbine that keeps its atmospheric instruments ticking as the snowdrifts pile up.The first Antarctica Day was December 1, 1959, when twelve nations peacefully agreed to dedicate Earth's southernmost continent to the pursuit of science by signing the Antarctic Treaty. That agreement, adopted by both the US and the USSR amid the accelerating Cold War, stands 60 years later as an important landmark in global relations and has expanded to include 54 countries.
