Planetariums have long served as a bridge between the night sky and the public imagination, combining astronomy, engineering, and design in a single space built for learning and reflection.Planetariums have long served as a bridge between the night sky and the public imagination, combining astronomy, engineering, and design in a single space built for learning and reflection. This book traces their development from early mechanical star projectors to the digital systems used in modern institutions today. You will learn how planetariums work, how they are designed and built, and how they have evolved to serve education, research, and public engagement over time. The book also examines the people and institutions that shaped this history, along with the technical principles behind dome projection and celestial simulation. Written with a clear and accessible approach, this guide is intended for readers who want a solid, factual introduction to the subject.
