Quotation taken from Galileo's Sidereus Nuncius (Astronomical Message).

Announcing the discovery in 1610 of what would come to be known as the Galilean Moons of Jupiter (Callisto, Europa, Ganymede, and Io):

"It remains for us to reveal and make known what appears to be most important in the present matter: four planets never seen from the beginning of the world right up to our day, the occasion of their discovery and observation, their positions, and the observations made over the past 2 months concerning their behavior and changes. And I call on all astronomers to devote themselves to investigating and determining their periods."
