Hi aspirant, Astronomy is the study of everything in the universe beyond Earth's atmosphere. That includes objects we can see with our naked eyes, like the Sun , the Moon , the planets, and the stars . Astronomy is the scientific study of the stars, planets and other bodies that make up the universe. The scientists who work in this field, called astronomers, use data to develop theories about how the universe operates and when and how the celestial bodies came into existence.

Space is important because if in the future anything happened to our plant (earth) and it is no longer then we need to go  to study the space. Space also provides earth with valuable metals, rare objects and precious materials that can be used for medical research. These special things can help cure diseases and help us to survive.

Thank You.
