Astronomical studies involve the scientific examination of celestial objects, such as stars, planets, and galaxies. This field of research helps us understand the universe's structure, origins, and evolution. Astronomers use various tools, including telescopes and satellites, to observe and collect data about these distant entities. These studies also encompass the exploration of phenomena like black holes, supernovae, and cosmic radiation. By analyzing this information, scientists can develop theories about the universe's formation and its future. Notable figures in this field include Galileo Galilei and Carl Sagan, who contributed significantly to our understanding of space.
