The study of celestial objects, space, and the universe is called astronomy. It covers everything from stars, planets, and comets to galaxies and the origins and fate of the cosmos. Astronomers observe with telescopes, spacecraft, and other instruments, then build theories to explain how objects move, form, and interact across vast distances. The other fields focus on different areas: biology deals with living organisms, geography studies the Earth's surfaces and features, and environmental science looks at the environment and how natural and human systems interact on our planet.
