The term for a scientist who studies the stars is an astronomer. Astronomers investigate celestial phenomena such as planets, stars, galaxies, and the broader universe. Their work involves observing and analyzing data, often utilizing telescopes and advanced technologies to explore vast distances beyond our planet. One major area of study includes understanding the life cycles of stars, the structure of galaxies, and the behavior of cosmic events like supernovae or black holes. Astronomers contribute to significant scientific advancements, enhancing our understanding of the universe's origins, structure, and eventual fate, while sometimes even impacting technology development on Earth.
