High above Earth, astronauts aboard the International Space Station continue to witness what Don Pettit calls 'luminous dancing fairies'—brief, inexplicable flashes of light that cross their vision in the dark. These are not illusions but measurable physical events: cosmic rays, ancient high-energy particles streaming through the universe, occasionally collide with the human retina and deposit enough energy to trigger the perception of light. The phenomenon was first reported by Apollo crews decades ago and persists unchanged today, a quiet reminder that space is not empty but alive with invis
