How Did Galileo Galilei Enter The Telescope

Galileo Galilei was an esteemed astronomer who lived in the time of great discoveries. Galileo was born in Pisa, Italy on February 15th, 1564. He soon moved to Florence with his family where he began his education in a monastery in Vallombrosa. He enrolled in the University of Pisa seven years later to study medicine. However, Galileo soon became interested in mathematics and the physical sciences. This interest brought an end to his medical studies. He spent three years searching for a teaching position in Florence. At this time, Galileo wrote two treatises which made his name well known. In 1589, he was given a teaching position at the University of Pisa. Galileo’s father died in 1591 forcing him to leave Pisa and look for better work to support his family. Later, he found a job at the University of Padua. The year 1604 marked the beginning of his career in astronomy. He publicly declared himself a Copernican. Galileo Galilei made many discoveries that changed astronomy greatly. He used the telescope to observe the sky, he helped find information to support the Copernican theory, and he made many ground breaking discoveries that furthered the world’s astronomical knowledge.

Contrary to popular belief, Galileo did not invent the telescope. A Dutch lens grinder secured a patent in 1608 for a device that magnified distant objects by combining two lenses. The instrument was originally used for terrestrial purposes. Galileo was intrigued. He built a telescope of his own with a magnifying power of about forty. On August 25th, 1609, he presented his invention to the Venetian Senate, which received tremendous success. This accomplishment helped him obtain a lifelong contract at the University of Padua. Galileo used the telescope to further his knowledge of the sky. He was the first person to record observations of the sky that were made with a
