Io is one of the four moons Galileo found circling Jupiter in 1610 — the nearest to the planet, and the most alive: restless, luminous, never still. Long before it was a moon, Io was a figure from myth — a mortal caught between the attention of a god and the watchfulness of a queen, who travelled far and changed shape along the way.

Io circles Jupiter in roughly forty-two hours — closer and faster than any of its companions. We take it as a quiet reminder that the best work comes from staying close, moving quickly, and never quite standing still.
