                The main infrastructures of ROP Nakhon Ratchasima comprised of the Exhibition Hall, Observatory Tower and Office Building.

Exhibition Hall: Showcases 14 interactive astronomy exhibitions, aiming for self-learning through visitors’ own experience.

“14 Interactive Exhibition Zones”


The building is adjacent to the Planetarium, which comprises of temporary exhibition – showcasing interesting and familiar astronomical facts. Currently, the Solar System is on display, altogether with astronomy professional photographs taken by Thai people, and 10 interesting astronomical phenomena. In the innermost of the Planetarium sits the 10-metre Dome equipped with projectors in Full Dome Digital with high definition more than 12 million pixels

“Inside the Planetarium”

Observation Tower:
The 2-storey tower is situated behind an open area for mobile telescopes and astronomical phenomena with large crowds.

The second floor of the tower houses 5 high-definition telescopes with diametres between 5 – 14 inches. They are all well-preserved in the sliding roof. Right beside it is the outdoor terrace to accommodate observers up to 200 pax.

On the other side of the Observation Tower is a shell-shaped fiberglass dome with 18-foot diameter that opens up to 180 degrees, enabling to observe the all sky. It is equipped with 0.7-metre optical telescope – the largest in the Northeastern region and the 3rd largest in Thailand. This telescope is considered one of the most modern with highest quality in Thailand that serves mainly the general public. From this telescope, we can observe various objects in the sky such as Jupiter (largest planet in our Solar System), Saturn (planet with the most spectacular and largest ring in the Solar System), Andromeda Galaxy (our closest neighbor to the Milky Way), and Orion Nebula (large and brightest nebula) just to name a few.

“Observatory and 0.7-metre Telescope”


Office Building: Acts as the main operating facility for the ROP staff members.

Activities under ROP, Nakhon Ratchasima Projects

               In order to raise awareness and enthusiasm in science, disseminating equal access in astronomy for the general public and local schools, this is done through the main targets of NARIT including youth, teachers, public, and amateur astronomers.


Target: Youth

Children’s Day Activities

               Focusing on basic activities for kids to enjoy while learning through the thought-provoking process. Themes are customized and being adapted according to each year’s highlights and phenomena.


Astronomy on Tour

               Promoting analytical and scientific skills for youth across Northeastern Thailand. Disseminate learning opportunities to schools in the rural areas from the ROP. Activities come in different stations and lectures according to the astronomical curriculum of the Institute for the Promotion of Teaching Science and Technology (IPST), as well as night observation.


Science Week

               In Commemoration of HM King RAMA IV’s accurate prediction of the solar eclipse of August 18, 1868, the ROP, Nakhon Ratchasima is thus hosting the annual Science Week. Activities come in scientific experiment stations, planetarium visit, 14 astronomical exhibition zones, and night observation.


E-Saan Young Astronomers Training
