Galileo Was The First Person To Discover Jupiter's Moons

Did you know that Galileo was the first person to discover Jupiter’s moons?

Here are some things Galileo Galilei did to help influence science.
Galileo is most known for creating the first telescope, but that is not true. Galileo was the first person to use the telescope to look at the sky, but not to create the first. At the time the Netherlands was working on a device to see objects far away, and Galileo figured out how it worked, and made one of his own.

In January of 1610, he discovered four moons orbiting Jupiter( Jupiter has at least 69 moons). Galileo may have been the first person to look at the sky with a telescope, but not to invent the telescope.
At the time, it was strongly believed that the earth was the center of the universe, and that the sun and all the planets orbited it.

The Catholic Church did not like people going against their teaching by saying the sun was the center of the universe, so in 1633 Galileo was summoned before the Roman Inquisition, and was placed under house arrest for the rest of his life, because he advocated
