Princess Sirindhorn AstroPark

Princess Sirindhorn AstroPark is the National Astronomical Research Institute of Thailand's headquarters and its flagship public astronomy campus. Opened in 2020, the 83,200-square-metre site combines research and space-technology laboratories with a 160-seat, 17-metre digital planetarium, interactive astronomy exhibitions, solar-system learning paths, and a public observatory built around a 0.7-metre telescope. The planetarium and exhibition operate on a regular public schedule, while free Saturday-night observing is offered seasonally and group visits can add telescope and engineering experiences.
