The development of stellar astrophysics

The vast starry sky is magnificent and serene, profound and mysterious. Most of the stars we see are fixed stars, which illuminate the night sky’s beauty by burning themselves. The Sun, the closest star to us, serves as the primary energy source for life on Earth. This article will mainly describe the research methods and key findings in stellar physics, explore how studying stars helps us understand the universe, and attempt to answer the question of whether humanity is alone in the cosmos.
