Astronomy is the study of the universe, the celestial objects that make up the universe, and the processes that govern the life cycle of all those substances. Until the discovery of the telescope and the law of motion and gravity in the seventeenth century, astronomy was primarily concerned with the prediction and prediction of the positions of the sun, moon, and planets, primarily for calendar and astrological purposes, and later for navigation and scientific interest. It uses mathematics, physics, and chemistry to explain their origins and evolution. Interesting topics include planets, moons, stars, nebulas, galaxies, and comets. Astronomers use electronic magnetic radiation emitted from stars and other celestial objects, which may include visible light, UV, infrared and X-rays. Since light is the primary means of studying these things, binoculars are one of the most important tools for astronomers.
Astronomy is the observation and recording of events from the beginning of civilization. The earliest civilizations of recorded history made systematic observations of the night sky. These include Babylonians, Greeks, Indians, Egyptians, Nubians, Iranians, Chinese, Mayans, and many ancient indigenous peoples of America. Many of these observations were deeply involved with cultural and religious beliefs. In the past astronomy included divisions such as astronomy, heavenly navigation, observational astronomy, and calendar creation. Nowadays, professional astronomy is often said to be the same as astronomy. Also, gas and dust around and between stars have become the subject of much research. Studies of nuclear reactors that radiate energy from the stars have shown how the diversity of atoms in nature can originate from a universe that only hydrogen, helium, and lithium were discovered in the first few minutes of its existence.
Professional astronomy is divided into observational and theoretical disciplines. The ancient Greeks were particularly interested in astronomy and were able to calculate some impressive images such as the size and distance of the sun. Persian, Arab, and Chinese astronomers supported astronomy in the Middle Ages, while little progress was made in Europe. Observation Astronomy is focused on acquiring information from observations of astronomical objects. This information is then analyzed using the basic principles of physics. Involving the phenomena in the largest form is the study of the evolution of the universe, the universe.

There are big discoveries in astronomy today. The Hubble Space Telescope was launched in 1990 and continues to send distant images and data to the galaxy and the galaxy. This is one of the few sciences that it has. This is especially true for the detection and monitoring of transient events. Fascinating astronomers have helped with many important discoveries, such as the discovery of new comets.
