NAOJ Nobeyama Radio Observatory NOBEYAMA

Nobeyama
Radio Observatory

“Holy Place” of Japanese Radio Astronomy
Japanese radio astronomy that was born immediately after the war,
has remarkably developed into a global level in Nobeyama
with solar radio observations and cosmic radio observations
by 45-m radio telescope and so on.

45-m telescope

The 45-m telescope is one of the world's largest radio telescopes that observes in the millimeter (1mm-10mm) wavelengths. Using its large 45-m diameter aperture,the 45-m telescope is capable of collecting extremely weak signal from distant terrestrial objects.
