"You cannot teach a man anything; you can only help him find it within himself.
Astronomy (astronomy) is the science that observes celestial bodies to try to explain their origins, evolution, physical and chemical properties. It should not be confused with celestial mechanics, which is a limited and special field of astronomy.
Astronomy, to be more precise, is the science that studies orbital bodies and all observable phenomena that occur outside of the Earth's atmosphere, such as stars, planets, comets, polar lights, galaxies (celestial islands), and Cosmic microwave background radiation.
It studies the distribution, movement, chemical composition, evolution, physical properties and interactions of all kinds of matter in the universe.
