Variable starIts story
73 Ophiuchi is a yellow type-F variable about 179 light-years away, in the body of the Serpent Bearer. Hotter than the Sun and slightly unstable, its brightness shifts over time in gentle oscillations. The light now settling on human pupils travelled from the early nineteenth century, when the first railway lines in Europe were still being laid.
