巴比伦人怎样利用周期预报日食？
How did the Babylonians predict eclipses using cycles?
他们发现日食约每18年11天重复一次（'沙罗周期'），记录历史食象后就能推算未来哪些朔日可能发生日食，是人类最早的日月食预报。
They found eclipses repeat every ~18 years 11 days (the Saros cycle); logging past eclipses let them forecast which new moons might bring one—humanity's first eclipse prediction.

古埃及人怎样用天狼星定年？
How did ancient Egyptians use Sirius to mark the year?
天狼星在日出前首次重现（偕日升）恰逢尼罗河泛滥前夕，埃及人据此定出一年约365天的周期来安排农耕。
Sirius's first dawn reappearance (heliacal rising) coincided with the Nile's flood, so Egyptians used its ~365-day cycle to time farming.

日本的'七夕'节和星空有什么关系？
How is Japan's Tanabata festival related to the stars?
七夕源自中国牛郎织女传说，对应天鹰座的牵牛星（河鼓二）与天琴座的织女星，被银河分隔，只在七月七（旧历）隔河相会。
Tanabata comes from the Chinese Cowherd-and-Weaver myth: Altair (in Aquila) and Vega (in Lyra) split by the Milky Way meet only on the 7th night—a star-crossed lovers tale.

韩国和中国的传统天文有哪些相似之处？
How is traditional Korean astronomy similar to China's?
古代朝鲜长期使用中国的二十八宿与浑天体系，并建有瞻星台（如庆州瞻星台），其历法多承自中原，星图也以中国星官为主。
Ancient Korea used China's 28-mansion and celestial-sphere system, built observatories like Cheomseongdae, and inherited calendars and star charts centered on Chinese asterisms.

为什么许多亚洲古文明都不约而同地重视北极星？
Why did many Asian civilizations all prize the pole star?
北极星几乎不动，是天然的'天轴'标记，便于定向、定季节和建立坐标；中国、印度、阿拉伯都把它作为星图与导航的基准点。
The pole star barely moves, a natural mark of the sky's axis, handy for orientation, seasons and coordinates; China, India and Arabia all used it as a navigational and charting reference.

古印度天文学有哪些特点？
What were the features of ancient Indian astronomy?
印度很早就用27（或28）'月站'(nakshatra)跟踪月亮，并精确算出交点月、恒星年；其数学通过阿拉伯传入，影响了后来的伊斯兰历算。
India early used 27–28 lunar stations (nakshatra) to track the Moon and computed the nodal month and sidereal year precisely; its math later reached and influenced Islamic astronomy via Arabia.

阿拉伯黄金时代的天文学贡献是什么？
What did the Islamic Golden Age contribute to astronomy?
阿拉伯学者保存并发展了希腊天文学，建造大天文台、编制精确星表（如《托莱多表》），发明平面星盘，并最早用代数方法处理天文计算。
Islamic scholars preserved and advanced Greek astronomy, built great observatories, compiled precise star tables (e.g., the Toledo Tables), invented the planispheric astrolabe, and applied algebra to astronomy.
