What is Astronomy?
The Planetary Society:
Astronomy is a scientific study of celestial object that include galaxies, comets, stars and planets. It is also a phenomenon that evolves outside the atmosphere of the earth like the cosmic background radiation. Apart from this, Astronomy is also concerned with the physics, evolution, meteorology, chemistry and motion of the celestial objects and also the development and formation of the universe.
