为什么中国用'二十八宿'而西方用'黄道十二宫'?
Why did China develop 28 mansions while the West developed 12 zodiac signs?
中国以月亮约27.3天绕天一周来划分月站(28宿),重视月与行星的行度;西方以太阳周年路径分12段,重视太阳与黄道带,反映了各自观测重点。
China divided the sky by the Moon's ~27.3-day path (28 mansions), focusing on lunar and planetary motion; the West divided the Sun's annual path into 12, focusing on the ecliptic—reflecting different priorities.

#二十八宿 #黄道十二宫
北斗七星在中国和西方的名字一样吗?
Do the Big Dipper's seven stars have the same names in China and the West?
西方把七颗星看作大熊座的一部分(尾巴),中国则独立称为'北斗',并据其形状定出'斗柄指东,天下皆春'等季节规律。
The West sees them as part of the Great Bear's tail; China calls them the Northern Dipper and used its handle's pointing to mark seasons ('when the handle points east, spring comes').

#北斗七星 #中西对比
占星学的黄道十二宫和天文学真正的星座对得上吗?
Do astrology's twelve zodiac signs match the real astronomical constellations?
由于岁差,春分点已西移约30度,今天的'白羊座'时段其实太阳位于双鱼座;且各星座大小不均,十二宫只是人为等分,与真实星空并不吻合。
Because of precession the vernal point has shifted ~30°, so the 'Aries' period now finds the Sun in Pisces; the 12 signs are equal slices that don't match the unequal real constellations.

为什么星星组成的图案其实并不在一起?
Why do the stars in a constellation pattern not actually lie together?
星座只是从地球看过去方向接近的投影,成员星可能相距光年之遥、彼此毫无关联,只是恰好出现在同一视线方向。
A constellation is just a projection of stars that happen to share a viewing direction from Earth; its members may be light-years apart and physically unrelated.

南半球的星空和北半球一样吗?
Is the night sky in the Southern Hemisphere the same as in the North?
不一样。南半球能看到北极星看不到的南十字座、大小麦哲伦云,而北半球常见的北斗七星在南纬较高处就沉到地平线下。
No. The South sees the Southern Cross and Magellanic Clouds invisible from the North, while the Big Dipper sinks below the horizon at southern latitudes.

为什么星星好像会'眨眼睛'?
Why do stars seem to twinkle?
星光穿过地球动荡、冷热不均的大气层时被折射得忽明忽暗,就像隔着热水汽看灯光;行星因为是个小圆面,反而不太眨眼。
Starlight bends through Earth's turbulent, uneven air, flickering like a light seen through heat haze; planets show a disc, so they hardly twinkle.

不同文明看到的星座一样吗?
Do different civilizations see the same constellations?
星星位置相同,但连线与故事各异:希腊人看猎户,中国人把相近星群划入'参宿'和'白虎',因纽特人则按极地生活看出驯鹿与海豹。
The stars are the same, but the lines and stories differ: Greeks saw Orion, Chinese grouped them into Shen and the White Tiger, and Inuit saw caribou and seals from polar life.
