I believe that at the time of Galileo and other pioneers in astronomy there was no formal astronomy study; he (and others) must have learned most of what they knew by themselves.

Philosophy, astronomy, and physics.
Galileo Galilei was an Italian polymath who lived in the 16th and 17th centuries. He made significant contributions to the fields of physics, astronomy, and mathematics. Galileo is often referred to as the "father of observational astronomy" for his pioneering use of telescopes to study the night sky.
Galileo left medicine to study mathematics, physics, and astronomy. He became known for his groundbreaking work in these fields and played a key role in the Scientific Revolution.
The Italian who first used a telescope to study astronomy was Galileo Galilei, born in 1564, the same year as William Shakespeare. Galileo is renowned for his significant contributions to observational astronomy, including the discovery of the moons of Jupiter and the phases of Venus. His work laid the foundation for modern physics and astronomy, challenging the geocentric model of the universe.
