  2. galileo • Galileo was born on February 15, 1564 and died January 8, 1642. he was an Italian scientist. • Galileo was an astronomer and he made improvements to the telescope. • He is called “The Father of Modern Observational Astronomy.”

  3. Galilean moons • Galileo discovered the phases of venus, which are different variations of lighting seen on the planets surface. • Galileo discovered the four largest moons of Jupiter. They named them the Galilean Moons.

  4. discoveries • Galileo was one of the first scientists to discover sun spots. • Galileo was the first person to report seeing craters and mountains on the moon. • Galileo tried to measure the size of the mountains and that is how he came to the thought that the moon was "rough and uneven, and just like the surface of the Earth itself,” .

  5. More discoveries • Galileo tried to figure out how the tide worked. • Galileo thought the tides were caused by the sloshing back and forth of water in the oceans as a point on the Earth's surface speeding up and slowing down because of the Earth's rotation on its axis and revolution around the Sun. • If his therory was correct there would be only one high tide a day, and there is two.

  6. Galileo and today • We still the the telescope that he designed. • He was right about the moon and its mountains.
