Astronomy For Beginners: The Introduction Guide To Space, Cosmos, Galaxies And Celestial Bodies, Paperback/Sally R. Ball

Astronomy is inherently more observational rather than an elemental study of science. All measurements are performed at a greater distance from the object of interest, with no control of quantities such as chemical composition, pressure, or temperature. You will also understand the study of the solar system with relation to the gravitational attraction that holds the planets in their elliptical orbits around the sun. An early study of the universe was done through the naked eyes. This method led to the categorization of the celestial bodies and assigned constellations. Constellation has been a very important navigational tool since the beginning of the world. Various disciplines of Astronomy will also be discussed. Examples of such disciplines include: - Astrophysics - Galactic astronomy - Galaxy Formation - Cosmology - Astrometry - Extragalactic astronomy - Stellar astronomy - Planetary sciences - Astrobiology - Formation of stars
