Planetarium

Planetarium is a highly specialized system that projects 360-degree immersive 3D visuals inside a dome structure using computer-controlled multiple projection devices or a fisheye lens. It enables large audiences to simultaneously explore our place in the universe, the Milky Way, and various celestial objects.

The primary reason for conducting sky observation inside a dome (planetarium) rather than outdoors is light pollution and the lack of sufficient observational equipment. Even under ideal weather conditions and reduced light pollution, observations remain limited by the capabilities of telescopes.

By using a digital planetarium, high-resolution images captured by powerful telescopes can be experienced in 3D within the dome. Thanks to digital technology, stars and celestial objects can be zoomed in and examined in great detail. With multimedia integration—video, animation, music, and sound effects—planetariums offer rich, engaging, and scientifically accurate presentations.

Planetariums are used to make space science more accessible in daily life and to present it in an engaging, hands-on way for children and young audiences. There are inflatable and portable planetariums that can be installed in indoor spaces, as well as permanent installations commonly found in large science museums and institutions.
