Astronomy is a natural science that studies celestial objects and phenomena. She uses mathematics, physics and chemistry to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Astronomy is a very useful science, one of the most ancient. Astronomy is needed to study the origin and development of celestial bodies and their systems, the structure, physical properties and chemical composition of celestial objects. This whole history of astronomy can be divided into transitions:
The current state of astronomy is associated with a sharp scientific and technological progress that occurred in the twentieth century. The development of rocket technology has made it possible to fly into space.
Currently, astronomy allows humanity to gain new knowledge and opportunities beyond the borders of its earthly cradle. Astronomy allows you to find out the trajectory of asteroids and meteorites that can be dangerous for our planet.
Astronomy in our time is closely connected with the development of cosmonautics and rocket science, the study of the planets of both the Solar System and other Earth-like exoplanets being discovered.
