When was tha stars discovered?

Stars have been observed by humans for thousands of years, with ancient civilizations like the Babylonians and Greeks documenting their existence as early as 3000 BCE. However, the scientific understanding of stars began to develop in the 17th century with the advent of telescopes. Galileo Galilei's observations in the early 1600s marked a significant advancement in the study of stars. The discovery of their composition and processes came much later, particularly in the 19th and 20th centuries with advancements in spectroscopy and astrophysics.
