About Nobeyama Radio Observatory
The Nobeyama Radio Observatory (NRO) operates the 45-m Radio Telescope that is one of the largest telescopes for millimeter wave observations in the world. Radio telescopes can reveal the structures of the Universe that we cannot see with our own eyes. For example, a radio map of the interstellar medium in our galaxy enables us to investigate how various stars are formed. Until today, the 45-m telescope has obtained significant results such as detecting signature of an intermediate mass black hole near the center of our galaxy and exploring the formation process of bio-molecules. The 45-m telescope continues to to unveil the invisible Universe.

The 45-m radio telescope
The Nobeyama 45-m Radio Telescope boasts one of the world's largest apertures for radio telescopes observing the radio waves known as "millimeter waves." It has led Japanese radio astronomy since its completion in 1982.
Nobeyama Radio Polarimeters
This instrument measures the intensity and orientation (polarization) of radio waves emitted from the full solar disk to monitor the state of solar activity.
The Nobeyama Radioheliograph is a radio telescope dedicated to solar observations. Using 84 antennas, it realizes a resolution equivalent to a radio telescope with a diameter of 500 meters.
Nobeyama Millimeter Array
The Millimeter Array observed with 6 antennas simultaneously and captured astronomical images with a resolution equivalent to radio telescopes with diameters of up to about 600 meters at maximum. Science operation has finished.
