- The phases of Venus.
- Jupiter’s moons.
- The stars of the Milky Way.
- The first pendulum clock.
What are Galileo’s 4 findings?
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.
What was Galileo’s big discovery?
Of all of his telescope discoveries, he is perhaps most known for his discovery of the four most massive moons of Jupiter, now known as the Galilean moons: Io, Ganymede, Europa and Callisto. When NASA sent a mission to Jupiter in the 1990s, it was called Galileo in honor of the famed astronomer.
Who was Galileo’s wife?
Galileo had three children with a woman named Marina Gamba, who he never married.
Who discovered Earth?
The first person to determine the size of Earth was Eratosthenes of Cyrene, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations.
Who discovered the Moon?
1. Galileo Galilei. Galileo wasn’t the first person to telescopically observe the Moon (that honor goes to Thomas Harriot, whose work was unknown for hundreds of years).
What planet did Galileo find in 1610 that he thought he was seeing 3 planets?
To Galileo’s surprise, Saturn wasn’t just one planet, but three! A big middle planet with a small planet or moon on each side, and the three were almost touching. Galileo drew it like this: Other astronomers, whose telescopes were not as good as Galileo’s, saw a single oval planet.

What did Galileo’s telescope reveal?
With this telescope, he was able to look at the moon, discover the four satellites of Jupiter, observe a supernova, verify the phases of Venus, and discover sunspots. His discoveries proved the Copernican system which states that the earth and other planets revolve around the sun.
What did Galileo discover about Jupiter?
In 1610, Galileo Galilei turned his rudimentary telescope on Jupiter, and realized that it had 4 large moons orbiting it: Io, Europa, Ganymede and Callisto. This was an important discovery, because it demonstrated that Earth was not the center of the Universe as proponents of the geocentric view believed.
Why did Galileo not marry Marina Gamba?
In Florentine society, the two main options for unmarried women of respectable families were either to enter a convent or to marry. Galileo did not marry his children’s mother, Marina Gamba, for it would not have been an honorable arrangement.
Why did Galileo not marry Marina?
Galileo had three children out of wedlock with Marina Gamba—two daughters and a son. The two young girls, whether by their illegitimate birth or Galileo’s inability to provide a suitable dowry, were deemed unfit for marriage and placed in a convent together for life.
