What 3 things did Galileo discover?
What did Galileo discover?
- Craters and mountains on the Moon. The Moon’s surface was not smooth and perfect as received wisdom had claimed but rough, with mountains and craters whose shadows changed with the position of the Sun.
- The phases of Venus.
- Jupiter’s moons.
- The stars of the Milky Way.
- The first pendulum clock.
What happened to Copernicus and Galileo?
Copernicus faced no persecution when he was alive because he died shortly after publishing his book. Galileo, on the other hand, was tried by the Inquisition after his book was published. Both scientists held the same theory that the Earth revolved around the sun, a theory now known to be true.

Who discovered the moon?
Galileo Galilei
Galileo’s discovery When the moon was named, people only knew about our moon. That all changed in 1610 when an Italian astronomer called Galileo Galilei discovered what we now know are the four largest moons of Jupiter.
Did Galileo prove Copernicus right?
Galileo discovered evidence to support Copernicus’ heliocentric theory when he observed four moons in orbit around Jupiter. Over time Galileo deduced that the “stars” were in fact moons in orbit around Jupiter.
What did Galileo prove?
Galileo sparked the birth of modern astronomy with his observations of the Moon, phases of Venus, moons around Jupiter, sunspots, and the news that seemingly countless individual stars make up the Milky Way Galaxy.
Who is science mother?
Science as a whole
| Field | Person/s considered “father” or “mother” |
|---|---|
| Science (modern) | Galileo Galilei (1564–1642) |
| Science (ancient) | Thales (c. 624/623 – c. 548/545 BC) |
How did Galileo contribute to the heliocentrism debate?
Galileo and Heliocentrism The phases of Venus, sunspots and comets were three phenomena that played an important role in debates about heliocentrism in the seventeenth century. Each group investigated one of these phenomena and how Galileo or one of his contemporaries interpreted it.
What did Galileo Galilei do with his telescope?
Galileo Galilei (1564-1642) was part of a small group of astronomers who turned telescopes towards the heavens. After hearing about the “Danish perspective glass” in 1609, Galileo constructed his own telescope. He subsequently demonstrated the telescope in Venice. His demonstration of the telescope earned him a lifetime lectureship.
How did Galileo’s observations change our understanding of the cosmos?
The story of Galileo’s telescopic observations illustrates how a tool for seeing and collecting evidence can dramatically change our understanding of the cosmos. Early telescopes were primarily used for making Earth-bound observations, such as surveying and military tactics.
Why was Galileo confined to bed for so long?
Galileo was confined to bed due to illness during the period when the comet was visible, so the evidence that he had to gather was mostly from observations of his contemporaries, especially those of Tycho Brahe. The measurements made by Tycho stated that comets were heavenly bodies.
