On 19 March, he sent the telescope he had used to first view Jupiter's moons to the Grand Duke, along with an official copy of Sidereus Nuncius (The Starry Messenger) that, following the secretary's advice, named the four moons the Medician Stars. [6] In his dedicatory introduction, Galileo wrote:
Galileo began his telescopic observations in the later part of 1609, and by March 1610 was able to publish a small book, The Starry Messenger (Sidereus Nuncius), describing some of his discoveries: mountains on the Moon, lesser moons in orbit around Jupiter, and the resolution of what had been thought to be very cloudy masses in the sky (nebulae) into collections of stars too faint to see ...
Galileo's sketch of mountains on the sickle Moon, as published in Sidereus Nuncius In philosophy of science , the Duhem–Quine thesis , also called the Duhem–Quine problem , says that unambiguous falsifications of a scientific hypothesis are impossible, because an empirical test of the hypothesis requires one or more background assumptions.

However, in the Discourse on Comets Galileo defended a view that posed no challenge to the main tenets of Aristotelian cosmology, while Grassi had in fact departed from the strictly ...
