Initially visible to those in the Southern Hemisphere earlier, the comet is now embarking on its exit from the inner solar system, soon to unveil its icy beauty to observers in the Northern Hemisphere from mid-October through early November, as confirmed by NASA.奥罗拉彗星来自遥远的太空深处，已完成了向太阳的旅程，并于9月27日到达近日点。最初仅在南半球可见，现在它正开始离开内太阳系，NASA证实，从10月中旬至11月初，北半球的观测者将能一睹其冰晶之美。 This weekend, the comet will grace our celestial neighborhood, approaching within a mere 44 million miles of Earth. Documented as its inaugural flyby past our planet, Comet Aurora flaunts an extraordinary 80,000-year orbit, presenting a cosmic display reminiscent of eras long past. To catch a glimpse of this astronomical marvel, stargazers are advised to turn their gazes westward post-sunset, where Comet Aurora will manifest as a luminous fireball in the night sky, accentuated by a trailing tail of cosmic allure. For enhanced viewing pleasure, NASA's Bill Cooke recommends the use of binoculars, promising an awe-inspiring experience under the cosmic canopy.本周末，这颗彗星将光临我们的天宇近邻，距离地球仅4400万公里。作为首次掠过我们星球的记录，奥罗拉彗星拥有长达8万年的轨道周期，呈现出一场令人联想到遥远时代的宇宙奇观。为了捕捉这一天文奇观，天文爱好者们建议在日落后将目光转向西方，奥罗拉彗星将在夜空中显现为一颗发光的火球，其尾部拖着迷人的宇宙光辉。为了获得更佳的观赏体验，NASA的比尔·库克建议使用双筒望远镜，承诺在宇宙天幕下带来令人震撼的体验。 Originating from the distant reaches of the Oort Cloud, Comet Aurora was uncovered in 2023 by vigilant observers at China's Tsuchinshan Observatory and the ATLAS telescope in South Africa, as recounted by NASA. An ancient wanderer composed of ice, gases, and rocks, this cosmic voyager has braved the solar journey intact, showcasing a remarkable display of resilience and beauty.据NASA所述，奥罗拉彗星源自遥远的奥尔特云，于2023年被中国紫金山天文台和南非ATLAS望远镜的敏锐观测者发现。这颗由冰、气体和岩石组成的古老漫游者，完好无损地完成了太阳之旅，展现了惊人的坚韧与美丽。 As Comet Aurora prepares to dazzle Earth with its luminous presence, astronomers anticipate a display of forward scattering, granting the comet a radiant glow as it reflects sunlight off its gaseous veil. While Wednesday promises the comet's brightest show, the sun's glare may momentarily obscure its splendor, hinting at a delayed celestial reveal that promises a truly mesmerizing sight to behold. For those unable to witness Comet Aurora's cosmic ballet firsthand, the Virtual Telescope Project in Italy offers a front-row seat to this celestial performance, showcasing the comet at its brightest on Wednesday and at its closest distance to Earth on Saturday. As we prepare to witness this extraordinary event, let us revel in the beauty of the cosmos and the grandeur of these celestial wanderers.随着奥罗拉彗星准备以其光芒四射的姿态照亮地球，天文学家们期待着出现前向散射现象，使彗星在其气态面纱上反射阳光而熠熠生辉。虽然周三将是彗星最亮的时候，但阳光可能会暂时掩盖其辉煌，预示着这场延迟的天文展示将带来真正令人着迷的景象。对于那些无法亲眼目睹奥罗拉彗星宇宙芭蕾的人来说，意大利的虚拟望远镜项目提供了前排座位，将在周三展示彗星最亮的时刻，并在周六展示其最接近地球的时刻。在我们准备见证这一非凡事件之际，让我们沉醉于宇宙之美以及这些天体漫游者的壮丽之中。 What are the key scientific facts surrounding Comet Aurora?关于奥罗拉彗星的关键科学事实是什么？ Comet Aurora, also designated as C/2023 A3 Tsuchinshan–ATLAS, boasts a fascinating 80,000-year orbit, making this encounter with Earth an exceptionally rare occurrence.
