An Eco-sustainable World


AstronomiaAstronomy is the science that deals with the study of celestial bodies, such as stars, planets, comets, galaxies and other objects present in the universe. Astronomers observe and analyze the universe outside Earth, trying to understand its structure, composition, origin and evolution. Astronomy encompasses a wide range of sub-disciplines, including observational astronomy, which involves the direct observation of celestial objects, and theoretical astronomy, which relies on mathematical and theoretical models to explain celestial phenomena.
The term astronomy comes from the Latin astronomĭa, which in turn comes from the Greek ἀστρονομία (‘astronomy’ composed of ἄστρον ‘astron’ «star» and νόμος ‘nomos’ «law, norm»).
Astronomers use instruments such as telescopes, radio telescopes, satellites, and space probes to collect data about the universe. Astronomy has contributed significantly to our understanding of the origin of the universe, the formation of stars and planets, the movements of celestial bodies, and many other aspects of the universe. It is also an interdisciplinary science that often overlaps with other disciplines such as physics, chemistry, geology and mathematics to solve complex astronomical problems.
Astronomy is one of the oldest sciences and continues to generate great interest and enthusiasm among scientists and the general public, contributing to our view of the universe and the search for life beyond Earth.
