Detail
`In September 1995, Bohyunsan Optical Astronomy Observatory, expected to greatly stimulate the advancement of Korea`s optical astronomy, is to be dedicated. It is located on a site of 29,900sq. meters on top of Mt. Bohyun near Youngchun City, Kyongsangbuk-do. Bohynsan Optical Astronomy Observatory houses a 1.8m reflector and a solar flare telescope. The reflector in equipped with a number of sophisticated instructure including a CCD camera (high-power electronic camera for astronomical observation), a medium dispersion spectrograph (for observation of astronomical spectra) and a speckle camera (a high-resolution instrument for astronomical observation). The 1.8m reflecting telescope has a nine times stronger focusing power and can thus see much deeper into space than the nation`s current largest telescope in thd existing Sobaeksan Astronomical Observatory, which has a mirror 60cm in diameter. For the first time in Korea, spectroscopic observation, essential to reserch into the physical properties and chemical elements of celestial bodies such as their temperature, pressure and constituents, will become possible. The solar flare telescope, composed of two 20cm and two 15cm refactors, will measure the solar spectra on four different wavelengths at the same time. Therefore, it will analyze the strength of the sun`s magnetic field and motions of particles in the solar atmosphere. The ensuing reserch finding will serve as a springboard for the development of astrophysics in korea. The observatory will be utilized for the astronomical reserch. By providing opportunities for school groups and the general public to visit the observatory, it is hoped to inspire interest and curiosity about the heavens and the universe. The facility will also contribute to the development of basic science in Korea by serving as a hot bed for reserch and its provision to scientists of the latest findings of astronomy. The Ministry of Information and Communication is issuing a commemorative stamp to mark the occasion, hoping that Bohyunsan Observatory`s dedication will inspire the development of Korean astronomy and a Korean aerospace industry in the coming 21st century.`
