telescope
Historically, it was the optical telescope. Modern radio telescopes, and cameras mounted on satellites, have advanced astronomy even further.
Though Galileo did not invent the telescope, he improved it greatly, and he used his new and improved telescope to discover and document a number of astronomical phenomenon. His work opened the door to astronomy wide, and we are fortunate he and others stepped through. An example of the power of his improved instrument was his discovery of the four most massive moons of Jupiter, and they are called the Galilean Moons in his honor.
Most famously he improved the telescope. His studied Astronomy with his telescope.
At the time of the scientific revolution, sources of knowledge dealing primarily with mathematics and astronomy were most often referred to. The scientific revolution began in the mid-1500s.

Most important for astronomy is to study physics and maths. There are many different fields of astronomy from the instrument building teams who work with their hands to the theoretical branches where mathematical ability and physical intuition is essential. In all branches of astronomy, and indeed life, good programming skills are invaluable. Perhaps the most essential ingredient is curiosity and the ability to search out answers.
Benjamin Franklin used his knowledge of astronomy to publish "Poor Richard's Almanac," a widely popular publication that contained weather forecasts, household tips, and witty sayings. Franklin's almanac became one of the most widely read publications in the American colonies during the 18th century.
As one of the sciences astronomy is most closely related to mathematics, physics and chemistry.
The most improved team is the Lakers.
There are more astronomy teachers than any other kind of astronomers.
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.
