Galileo Galilei: An Astronomer In The 17th Century
Galileo Galilei was an astronomer in the 17th century. Galileo has played a key role in philosophy and science. Because Galileo observed that space was much bigger than thought by astronomers before him, he is very important to modern science today.
Galileo Galilei was born on February 15, 1564, in Pisa, Italy. Some important historical event that happened throughout his lifetime are in 1567 millions of Native Americans are killed by disease. In 1597, Shakespeare's play, Romeo and Juliet is published. Finally, in 1636, Harvard University was founded.
Galileo Galilei was the first of six children to Vincenzo Galilei and Giulia Ammannati. In the 1570's Galileo's family moved to Florence, Italy. When he lived in Italy, art, science, literature …show more content…
He made many inventions to contribute to the area of science. Galileo's inventions include; the thermoscope and pendulum clock. Galileo also improved upon the spyglass and the telescope.
In 1609, Galileo built the first version of his telescope. He is often incorrectly credited with the invention of the first telescope. Galileo only improved the telescope and made his own. He modeled his telescope by the ones that were made in other parts of Europe. The first telescope was made by Hans Lippershey. The telescopes that were in other parts of Europe could magnify up to three times.
Once Galileo Galilei heard about the telescope he started, right away, to engineer a better improved version of it. His version of the telescope was almost identical to the way opera glasses worked. He made his telescope by having concave lenses in the back and convex lenses in the front. Galileo's new and improved telescope can magnify up to twenty times. He also grinded his own lenses and changed the ways the lenses were arranged. Galileo Galilei found many new discoveries in outer-space with the telescope he …show more content…
The telescope had a magnification of up to twenty times. He discovered these moon's around December 1609 or January 1610. Galileo rote the letter that said he discovered Jupiter's moons on January 7, 1609. Galileo named the four moons, also known as satellites, Ganymede, Callisto, Europa, and Lo. He studied the planet, Jupiter, of the course of one month and found the route each one of the moons take. Galileo wrote about the moons in his book named, Siderius Nuncius. The moon named Lo, is the fourth largest moon in the universe. This moon also has around 400 volcanoes that are active, 200 mountains, and it has a very thin atmosphere. Europa is the smallest of the four moons and is one of the smoothest moon in the Solar System. Europa is covered in water that is frozen over. Ganymede is the largest moon in the Solar System and it's diameter is 5262.4 kilometers. It is covered in craters and in ice. Callisto is the farthest moon away from Jupiter. This moon is the third largest moon in the Solar System and is the second largest out of the four
