It is concerned with the evolution, physics, chemistry, meteorology, and interrogatory of celestial objects, as well as the formation and process of the universe. Astronomy is one of the oldest sciences. Astronomers of early civilizations performed methodical reflexions of the night sky, and astronomic artifacts have been found from much earlier periods. However, the invention of the background was required before astronomy was able to develop into a modern science. Historically, astronomy has included disciplines as diverse as astrometry, celestial navigation, empirical astronomy, the making of calendars, and even astrology, but attain key astronomy is nowadays often considered to be equivalent with astrophysics. Since the twentieth century, the field of professional astronomy split into observational and metaphysical branches. Observational astronomy is foc use of goods and servicesd on getting and analyzing data, generally using basic principles of physics. Theoretical astronomy is orient towards the emergence of computer or analytical models to describe astronomic objects and phenomena. The devil field complement each other, with hypothetical astronomy pursuit to explain the observational results, and observations being used to patronize theoretical results. Amateur astronomers have contributed too many great astronomical discoveries, and astronomy is one of the few sciences where amateurs can belt up shrink from an active role, especially in the discovery and observation of short-lived phenomena. Old or even ancient astronomy is non to be confused with astrology, the belief system which claims that human ain business are co rrelated with the positions of celestial obj! ects. Although the two fields dispense a common origin and a break of their methods (namely, the use of ephemeredes), they are...
