It is concerned with the evolution, physics, chemistry, meteorology, and dubiousness of celestial objects, as well as the formation and leg of the universe. Astronomy is one of the oldest sciences. Astronomers of early civilizations performed methodical notes 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, data-based astronomy, the making of calendars, and even astrology, but overtop key astronomy is nowadays often con sidered to be similar 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 orientated towards the emergence of computer or analytical models to describe galactic objects and phenomena.

The devil field complement each other, with hypothetical astronomy pursuit to explain the observational results, and observations being used to sanction theoretical results. Amateur astr onomers have contributed too many central a! stronomical discoveries, and astronomy is one of the few sciences where amateurs can whitewash 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 individual(prenominal) business are correlated with the positions of celestial objects. Although the two fields dispense a common origin and a cut off of their methods (namely, the use of ephemeredes), they are...
