Space science is a field of science which primarily covers the study of universe. This science excludes the plane earth and its atmosphere. Basically this can be considered as astronomy. However now a days it includes the environment beyond 100 kilometers above the earth surface. This environment includes the sun, solar system planets, stars, galaxies, quasars, comets, radiation, electric and magnetic fields, plasma, and etc. Astronomy are subdivided to eight categories such as Astrophysics, Galactic Science, Stellar Science, non-Earth Planetary Science, Biology of Other Planets, Astronautics/Space Travel, Space Colonization and Space Defense. Due to the fast expanding of the coverage of astronomy, astrophysics became separated. Astrophysics is the study of physical properties and dynamic processes of celestial or astronomical objects.
