Stars are the sources of light. If they did not emit light, there would be no stars and thus no astronomy.

Sir Isaac Newton made significant discoveries in astronomy, including formulating the laws of motion and universal gravitation. He also developed the first practical reflecting telescope, known as the Newtonian telescope. Additionally, Newton's work in celestial mechanics laid the foundation for our understanding of the motion of planets and other celestial bodies.
Jack Newton has written: 'An Introduction to CCD Astronomy'
Sir Isaac Newton taught mathematics, physics and astronomy.
Newton contributed a Theoretical rational basis for Astronomical Motions. Prior basis for motion was religious or The Law of "Nature". Newton's Law of Gravity, revolutionized not only Astronomy, but Science.
Newton invented the reflector telescope in the 1680's.
the father of modern astronomy
He studied mathematics and astronomy.

Mainly Physics, but also astronomy
Sir Isaac newton had many hobbies, but the two main ones are astronomy and alchemy
He wants to find out more about Earth's gravity.
