Astronomy is the scientific study of celestial bodies in the visible universe, from the scale of a few meters to the macro scale, including the underlying physics governing those bodies. What they are made of, their properties, including distribution, relation, distance, movement, creation, age and demise.
With the progress of technology, that has dramatically improved our understanding of the universe. Astronomy has been one of the most modernized area of scientific study but also one of the oldest sciences, practiced by all ancient civilizations to some degree. Sadly people have increasingly started to lose connection with the observable universe, something that was previously even required for measuring time, define seasons. Astronomy is among our species first technological steps, but today only passingly remarked about when it verifies something thought about in theoretical physics. Even in a highly industrialized global civilization, defined by consumerism only few of us had the chance to go beyond simple images and concepts and have in considering what is around our blue dot and it's implications for us.
This Wikibook introduces the reader to that tapestry and the process that revealed it to humanity. It presents astronomy not only as a field of knowledge, but also as a human endeavor in science.
