What is Astronomy/meaning/concept/elaboration

Astronomy is the science that studies the universe as a whole, as well as its stars, movements and their evolution .The civilizations of the ancient world, especially the Egyptians and the Greeks of the Alexandrian period, were already concerned with knowing what was beyond the planet. Astronomers claim that all beings live in a universe full of energy and matter whose origin is largely unknown.

The purpose of astronomy is to describe the laws that govern the universe

Only 400 years ago astronomers have known about the existence of our planet, which revolves around a larger star: the Sun. Nicolaus Copernicus was a Polish astronomer and mathematician who developed the heliocentric theory of the Solar System . This theory is the fundamental principle of modern astronomy.

Astronomy was consolidated as scientific knowledge through Galileo’s telescopic observations in the 17th century, determining the phases of the Moon, the movement of the planets, as well as the principle of gravity and the force that governs the entire movement of the universe.

Through Galileo’s discoveries, astronomy incorporated a number of related disciplines.

On the one hand, theoretical astronomy describes the mathematical structures involved in the process of the cosmos. From this astronomical perspective, the formation of galaxies, stellar evolution and the question of relativity were studied (one of the theories that is part of this discipline is string theory).

Astrophysics is another strand of this science. It deals with the relationship between physical laws and the stars.

Theoretical astronomy, astrophysics and other branches of astronomy (eg celestial mechanics) seek to answer a series of questions that have not yet been definitively answered: what is there in the universe, whether there is intelligent life on other planets, whether there are other worlds and other questions that astronomers try to understand.

It can be said that astronomy is the science that observes the universe, both in its qualitative and quantitative dimensions.

For this reason, it is knowledge that is related to other branches and scientific disciplines such as mathematics, physics, geology, chemistry , electromagnetism, among others.
