Explanation: Do you know the names of some of the brightest stars? It’s likely that you do, even though some bright stars have names so old they date back to near the beginning of written language. Many world cultures have their own names for the brightest stars, and it is culturally and historically important to remember them. In the interest of clear global communication, however, the International Astronomical Union (IAU) has begun to designate standardized star names. Featured here in true color are the 25 brightest stars in the night sky, currently as seen by humans, coupled with their IAU-recognized names. Some star names have interesting meanings, including Sirius (“the scorcher” in Latin), Vega (“falling” in Arabic), and Antares (“rival to Mars” in Greek). You are likely even familiar with the name of at least one star too dim to make this list: Polaris.

说明: 你知道最明亮的一些恒星之芳名吗？你可能晓得，而有些亮星的名字极为古老，其定名可回溯到信史肇始之初。许多世界各地的文明，以不同的名字称呼这些最明亮的恒星，而且在文化和历史传承上，知道这些名称有其重要性。不过为了信息能交换无误，国际天文联盟（IAU）带头把恒星的名称标准化。上面这幅真实色彩的主题图像，呈现了在夜空中，目前人类眼里最明亮的25颗恒星及它们的IAU认可名称。有些恒星的名称带有相当有趣的含义，例如天狼星的拉丁文意为“大热天”，织女星的阿拉伯文意为“翔降之鹰”，而心宿二的希腊文意指“火星的对手”。此外，至少有一颗我们更熟悉的恒星─北极星，太暗而根本上不了这个榜。
