Astronomy is the study of the celestial sphere.
Since our early ancestors first contemplated the night sky, we have been striving to understand our place in the universe. Astronomy has it’s origins in religious and superstitious practices, such as astrology, as well as the need to predict the cycle of the seasons and the measurement of time. Over the centuries, astronomy developed into a disciplined science, and now encompasses many fields of study such as astrometry, cosmology, and astrophysics.
Amateur Astronomy is accessible to anyone, and can be practiced with a pair of binoculars, a small telescope or even the unaided eye, while the dedicated enthusiast might invest in more sophisticated and expensive equipment.
Astronomy has ties with many related scientific disciplines, from the largest scale, including the study of the structure and evolution of the universe as a whole, to the smallest scale of quantum mechanics and particle physics, which must be taken into account to explain the fundamental workings of the universe and the phenomena we observe through our telescopes.
