#Lantau#大屿山 之前购买过的，可以联系 @ljfxz 退款，直接发机场邮箱给他 剩余价值退款按照( 剩余时长*时长单价)+(剩余流量*流量单价)的形式退款 流量单价=套餐价格*0.8/套餐流量总数 时长单价=套餐价格*0.2/套餐时长总数 例如轻量套餐价格为9元，流量为80G,时长为30天。那天数单价为(0.2*9)/30，流量单价为(0.8*9)/80。 此时轻量用户还剩10天，流量还有70G，那退款为10*[(0.2*9)/30] + 70*[(0.8*9)/80] 注* 充了流量的钱也可退

🪐 In the constellation Hydra, astronomers have found R Hydrae, a star that pulses in brightness over a period of about 385 days. This "Mira variable" expands and contracts like a cosmic heartbeat, changing size and light output as it nears the end of its life, giving scientists clues about the future fate of our own Sun. ✨ #stars⚡#hydra⚡#pulsation⚡#nasa⚡#galaxy⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries

🪐 In the constellation Vela, the star system HD 74423 displays an unusual cosmic phenomenon: its shape is teardrop-like rather than round, caused by the powerful gravitational pull of a nearby red dwarf companion. This distortion leads to "heartbeat" pulsations—brightenings and dimmings in rhythm with the stars’ orbits—making HD 74423 the first known one-sided pulsating star in our galaxy. ✨ #Vela⚡#heartbeatstars⚡#pulsation⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries
