Solution

Space science is a branch of physics that helps unravel the mysteries of the universe. Space research makes use of a number of disciplines like physics, mechanical engineering, materials sciences, chemistry, biology, medicine, psychology, computer science and other fields of scientific knowledge. Astronomy is the scientific study of celestial objects, such as stars, planets, comets and galaxies. Through the use of physics, astronomy explains the evolution of the universe and through sound mathematical simulations it forecasts its development. Astrophysics deals with the physical properties of celestial bodies and with the interaction between matter and radiation in the interior of celestial bodies and in interstellar space.
