What is Radio Astronomy Observation?

We can see the stars of the universe by their light, while radio waves can observe the interstellar gas from which stars are born, and the supernova remnants which appear after a heavy star dies.

Radio observation allows us to see the dynamic changes in the universe in the birth and death of stars.

The Ministry of Internal Affairs and Communications has established, based on the Radio Law Article 56-1, eleven radio receiving facilities for radio astronomy services, including the National Astronomical Observatory, and has taken measures to ensure that the operation of these receiving facilities will not be obstructed.
