The Bangkok Planetarium, or ท้องฟ้าจำลอง กรุงเทพ, is Thailand’s first public planetarium and one of the leading destinations for astronomy education in Southeast Asia. Opened in 1964, it has long served as a center for inspiring scientific curiosity among children, students, and the general public.

The heart of the planetarium is its massive star dome theater, upgraded with a state-of-the-art full-dome digital projection system that delivers a stunningly realistic simulation of the night sky, deep space, and planetary movements. Audiences are taken on a mesmerizing journey across galaxies, black holes, solar systems, and cosmic phenomena, accompanied by engaging narration and breathtaking visuals.

Beyond the dome shows, the Bangkok Planetarium is part of the Science Centre for Education, which houses various interactive exhibits and hands-on activities. Visitors can learn about the solar system, star formations, lunar phases, and space missions through visually engaging and tactile displays that appeal to all age groups.

Key highlights include:

• An aquatic life exhibition simulating underwater environments

• A science fun zone designed specifically for young children

• STEM workshops, temporary exhibits, and special science events throughout the year

The planetarium regularly organizes special events such as Star Parties, themed science festivals, and mobile exhibitions, especially during school breaks and important astronomical dates.

Whether you're a curious child, a science enthusiast, or a tourist seeking something unique, the Bangkok Planetarium offers a rare chance to connect with the universe in an educational, exciting, and family-friendly environment.
