'''Astronomy''' is the science of observing the [[heaven]]s. It has been studied since ancient times, forming a major part of the religions of many early civilizations such as the [[Egpyt|Egyptians]] and the [[Aztecs]]. The great stone henge at [[Stonehenge]] in [[England]] is also thought to be an astronomical observatory. The handing down of complex astronomical teachings shows these early [[civilization]]s must have had formalized systems of [[education]].

'''Astronomy''' is the science of observing space and the objects in it (excluding Earth).

Astronomy was crucial to the development of [[safe]] and accurate [[navigation]] for ships, and observations of the movement of [[heaven|heavenly bodies]] lead to the theories we know call [[physics]]. In fact astronomy and physics are still somewhat merged, some scientists calling themselves astrophysicists.<br />

In fact, much of astronomy today relies physics, thus many astronomers are considered astrophysicists.<br />
