Galileo Galilei created the telescope, used persistence to innovate ways to overcome the church (that was against him and didn’t want him to study space) and continue with improving the telescope and making a major breakthrough on studies of space. Galilei is extremely famous for improving the telescope. Most people think he invented the telescope, but he actually learned about a telescope created by Dutch eyeglass makers and fixed it up and made his own, better version. Sailors learned about it and wanted some telescopes because they saw other ships better with it (Biography.com, 2017). Galilei looked up to the sky using his telescope in 1610 and spotted four objects around Jupiter, which turned out to be Jupiter’s moons (History.com, 2018).
