Just some romantic astronomy

"Two of the brightest stars in the night sky are Altair and Vega. And it is said they were deeply in love, but forever separated by celestial river of the Milky Way. But once a year on the seventh day on the seventh month, Vega cries so hard that all the magpies of the world fly up and create a bridge with their wings so the two lovers can be together for a single night of passion."
