The act or process of emerging or rising out, particularly from water; in astronomy, when a celestial body becomes visible after being hidden.
From Latin emersio, from emergere (e- 'out' + mergere 'to dip'). The suffix -ion creates a noun form describing the action or result of emerging.
Astronomers use 'emersion' to describe the exact moment a star reappears after being blocked by the moon—it's the opposite of 'immersion'—and timing these moments helped map the moon's surface.
