How did Galileo discover the phases of the Moon?
In the fall of 1609 Galileo began observing the heavens with instruments that magnified up to 20 times. In December he drew the Moon ’s phases as seen through the telescope, showing that the Moon’s surface is not smooth, as had been thought, but is rough and uneven.
How did Galileo prove heliocentrism?
Using his refracting telescope, Galileo observed in late 1609 that the surface of the Moon is not smooth. Early the next year, he observed the four largest moons of Jupiter. Later in 1610, he observed the phases of Venus—a proof of heliocentrism—as well as Saturn, though he thought the planet’s rings were two other planets.
Galilei satte solsystemet på plats Med hjälp av den upptäckte han månens kratrar, solfläckarna och Jupiters månar. Dessa upptäckter stödde Copernicus teorier som Galilei anslöt sig till. Dessa teorier gick ut på att solen är centrum och att jorden roterar runt denna stjärna.
