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 acquiring and analyzing data, generally using basic principles of physics. Theoretical astronomy is orientated towards the emergence of computer or analytical models to describe astronomical objects and phenomena.
The devil palm complement each other, with hypothetical astronomy pursuit to explain the observational results, and observations being used to nourish theoretica l results. Amateur astronomers have contribu! ted too many crucial astronomical discoveries, and astronomy is one of the few sciences where amateurs can withal 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 own(prenominal) business are correlated with the positions of celestial objects. Although the two fields dispense a common origin and a deviate of their methods (namely, the use of ephemeredes), they are...
