Astronomy is the study of the Sun, Moon, stars, planets, comets, galaxies, gas, dust, and other non-Earthly objects and phenomena. Observational astronomers focus on the direct study of stars, planets, and galaxies. Theoretical scientists analyze how systems might have evolved.
Astronomy is about very concrete, observable things. Cosmology involves the large-scale aspects of the universe, the esoteric, invisible, and sometimes completely theoretical things, like string theory, dark matter and dark energy, and the concept of multiple universes.
Astrochemistry is a branch of science that lies at the intersection of astronomy and chemistry. In this field, it studies chemical analysis and processes on gas clouds, stars, planets, galaxies and other celestial bodies in space. It uses the principles of chemistry to understand the composition, chemical reactions and evolution of celestial bodies. It tries to understand how chemistry works in the universe.
Star Chemistry:
It helps us understand how stars are formed, what chemical reactions take place inside them, and how these processes produce various elements. Stellar chemistry provides important clues to understanding the overall chemical composition of the universe and the evolution of these objects. Molecular clouds in space provide the material for the formation of new stars and planets.
Planetary Chemistry
The surface composition and atmospheres of planets and their moons are of interest to astrochemistry. Atmospheric chemistry studies the effects of planetary climates and chemical composition. Research in this field is aimed at understanding the chemical structure of planets, moons, and other celestial bodies within and outside the solar system. For example, the thick carbon dioxide atmosphere of Venus, the iron oxide-rich soils of Mars, and the hydrogen and helium atmosphere of Jupiter. The ratio of oxygen and nitrogen in the Earth's atmosphere has a significant effect on the sustainability of the atmosphere.
Gas Clouds and Nebulas:
These structures play a role in the formation of new stars and involve chemical evolution processes. Gas clouds and nebulae are dense clouds of gas and dust in space that can form colorful and visually striking structures that can be detected by astronomical observations. These celestial bodies often play a role in the formation of new stars and planets.
Meteorites and Meteoroids:
Meteorites and meteoroids, as natural celestial bodies from space, not only provide a brilliant spectacle in the sky, but also provide important information about the history and evolution of the Solar System. They are important sources for chemical analysis of materials in space. The minerals and elements found in these objects provide information about the evolution of the Solar System.
