Welcome to the official website of the Central Valley Astronomers
Astronomy is the scientific study of celestial objects such as stars, planets, comets, and galaxies, as well as the phenomena that occur outside Earth's atmosphere. It is a natural science that seeks to understand the universe and its components, including their origins, evolution, and behavior.
Astronomers use various tools and techniques to observe and study celestial objects. Telescopes, both ground-based and space-based, are fundamental instruments for collecting and analyzing light from distant objects. Other technologies, such as spectroscopy and radio astronomy, help astronomers gather additional information about the composition, temperature, and other properties of celestial bodies.
The field of astronomy encompasses a wide range of sub-disciplines, including observational astronomy, theoretical astronomy, astrophysics, and cosmology. Observational astronomers make observations of celestial objects, while theoretical astronomers develop models and theories to explain the observed phenomena. Astrophysics involves applying the principles of physics to understand the behavior of celestial bodies, while cosmology is the study of the larger-scale structure and evolution of the entire universe.
Whether you just want to learn a few star and constellation names, or you want to photograph the heavens in their beauty, or anything in between, we can help you explore the options and make this fun hobby your own. Our membership comprises amateurs, professionals, teachers, and professors. CVA members do visual astronomy, electronically-assisted astronomy, and astrophotography.
Our club meetings are a great way to meet our most active members face to face. Most meetings have an educational element, with a presentation by one of our members or a guest speaker, followed by coming events and general club business. Our dark sky star parties are the best way to learn about the various types of equipment available to amateur astronomers. We even do camping star parties up at Courtright Reservoir, for those who wish to experience the darkest skies available in the area for multiple nights.
If you are wondering how to get started, please give one of us a call or send us an e-Mail. If you have an interest in space, we want to help you achieve your goals! Astronomy is a rewarding hobby and a wonderful adventureAstronomy terms
