What is the role of astronomers?

Astronomers play a vital role in the exploration and understanding of the universe beyond our planet. Their primary focus is on studying stars, planets, comets, galaxies, and other celestial bodies, which provides insights into the fundamental laws of physics, the formation of celestial bodies, and the evolution of the universe. By analyzing light from these objects, astronomers can gather crucial data about their composition, distance, movement, and more.

The study of celestial bodies allows astronomers to address questions about the origins of the universe, the potential for life on other planets, and the dynamics of galaxies. Thus, their work significantly enhances our knowledge of the cosmos and contributes to advancements in various scientific fields, including physics, chemistry, and even planetary science.

In contrast, the other options involve aspects of Earth sciences or meteorology, which are not the primary focus of astronomy.
