Yecheon Astro-Space Center is a theme park that opened in November 2004. The Yecheon Astronomical Science and Culture Center has built and operated the Yecheon Star Observatory. Visitors can stay in the accommodations in the park, observe the distant universe through a large telescope, and experience the space environment such as weightlessness.

In the observation room, visitors can observe the appearance of the universe with a 508 mm (20 inch) reflecting telescope that is automatically controlled by a computer. In the auxiliary observation room, visitors can observe sunspots and huge pillars of fire on the surface of the sun with a quadruple solar telescope. The astronomical projection room is a 'space theater' where a digital astronomical projector and video projector are installed, and images related to the astronomical universe, including seasonal constellations, are screened on a hemispherical dome screen on the ceiling.

At the Yecheon Star Observatory, visitors can observe the pillars of fire that soar through the sun during the day and sunspots that are larger than Earth. At night, visitors can observe the galaxy, the nebula, where stars born and die, as well as star clusters, and the moon, which is the closest celestial body to Earth, has large and small meteorite craterson the surface. There are many more fun experiences at the Yecheon Star Observatory.
