Sidereus Nuncius, or The Sidereal Messenger

Why this matters here

Sidereus Nuncius announces telescopic findings—uneven lunar surface, resolved Milky Way, Jupiter’s companions—as public observational fact before institutions were prepared to treat them as such. When Authority Is Misread uses those moons as evidence that changed what “seeing” could force into the open. Galileo reports instruments rewriting the sky; the book asks what happens when new visibility arrives before legitimacy frameworks can absorb it.
