Core Viewpoint - The article discusses the mythological story of the Cowherd and the Weaver Girl, highlighting their annual meeting on the Qixi Festival, while explaining the astronomical reality that the stars representing them, Altair and Vega, are moving further apart in the universe [1][3]. Group 1: Astronomical Context - The stars representing the Cowherd and the Weaver Girl are Altair (He Gu Er) and Vega (Zhi Nu Yi), located in the constellations Aquila and Lyra respectively [5][6]. - Altair is situated on the "eastern bank" of the Milky Way, while Vega is on the "western bank," currently about 16 light-years apart, with a distance increase of approximately 28.7 kilometers per second [8][10]. - The distance between the two stars is increasing at a rate of about one-seventeenth of their original distance each year, which is not observable to the naked eye [12]. Group 2: Future Astronomical Changes - Due to axial precession, Vega may regain its status as the North Star in over 10,000 years, as the Earth's axis will eventually point towards it again [12]. - If Vega becomes the North Star, it will occupy a relatively fixed position in the sky, making it easier to observe throughout the year, unlike its current seasonal visibility [12].
