Astronomy is the study of celestial objects, including the stars and moons. It uses mathematics, physics, and chemistry to understand the properties and evolution of these objects. It also includes the study of meteors, comets, planets, and nebula. Learn more about the history of astronomy and how it affects our lives. To learn more, visit the National Geographic website. Here, you’ll find more information about astronomy and its history.
A large part of astronomy is related to observations from space. Many astronomers are scientists who have a background in physics, but amateur astronomers also contribute to scientific programmes. Amateur astrologers typically focus on visual observations of beautiful structures in the Universe, such as planets and stars. An astrology database might include a list of stars and their positions, while an astronomy database contains lists of known objects within that image.
Other branches of astronomy study the formation, structure, and life cycle of extraterrestrial objects. These include the sun, stars in the Milky Way galaxy, and other planets in the universe. Though observational science, cosmology focuses on theoretical subjects such as the origin of the universe, black holes, and the idea of multiple universes. The study of stars, particularly their life cycles, is another area of astronomy that can be studied.
