Its story

In Cygnus, above the river of the northern Milky Way, an orange class K star travels in from some 1006 light-years away. Its light set out around the year 1019, when China's Song dynasty was making early military use of gunpowder and the kingdoms of León and Castile were reorganising after the caliphates. The glow we see now crossed the entire Middle Ages before settling on the lens.
