Planetarium technology refers to advanced systems used to create immersive visual experiences of the night sky and celestial events. These systems often include high-resolution projectors, digital displays, and specialized software that simulate stars, planets, and other astronomical phenomena. Modern planetariums can also incorporate interactive elements, allowing visitors to explore the universe in real-time. Some facilities use virtual reality and augmented reality to enhance learning, making it easier for audiences to understand complex concepts in astronomy and space science.
