Galileo was an Italian astronomer, mathematician, physicist, philosopher and professor who made pioneering observations of nature with long-lasting implications for the study of physics. He also constructed a telescope and supported the Copernican theory, which supports a sun-centered solar system.

Who was an Italian astronomer who?
Galileo, in full Galileo Galilei, (born February 15, 1564, Pisa [Italy]—died January 8, 1642, Arcetri, near Florence), Italian natural philosopher, astronomer, and mathematician who made fundamental contributions to the sciences of motion, astronomy, and strength of materials and to the development of the scientific
Who was Galileo and what did he discover?
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.
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.
Why did Galileo become an astronomer?
He took a job teaching math to university students. Galileo was also interested in astronomy. He built a telescope to help him study the sky. Galileo first discovered that the Moon had mountains just like Earth.
Who first discovered heliocentrism?
Nicolaus Copernicus was a Polish astronomer known as the father of modern astronomy. He was the first modern European scientist to propose that Earth and other planets revolve around the sun, or the Heliocentric Theory of the universe.
What Galileo invented answer?
Galileo did invent a thermometer, called Galileo’s air thermometer (more accurately termed a thermoscope), in or before 1603. Another invention that Galileo worked on was a pendulum clock. Galileo inventions include telescope, pendulum clock.
When did Galileo make his discovery?
In 1609, using this early version of the telescope, Galileo became the first person to record observations of the sky made with the help of a telescope. He soon made his first astronomical discovery.
Who discovered Earth?
By around 500 B.C., most ancient Greeks believed that Earth was round, not flat. But they had no idea how big the planet is until about 240 B.C., when Eratosthenes devised a clever method of estimating its circumference.
Who discovered that the Earth revolves around the Sun?
Planet positioning But in the 1500s, Nicolaus Copernicus found that the movements could be predicted with a much simpler system of formulas if both Earth and the planets were orbiting the Sun.
