Kalyazin Radio Astronomy Observatory

Kalyazin Radio Astronomy Observatory operates a large parabolic dish for radio waves near the town of Kalyazin in Tver Oblast. The white metal dish sits on a rotating base and tilts toward different parts of the sky.

The facility was built in the early nineties as part of a center for satellite communication. Its commissioning expanded Russian research capacity in the field of radio astronomy considerably.

Scientists from multiple countries gather at this facility to conduct research on cosmic microwave background radiation, pulsars, and deep space communication signals.

The site sits outside built-up areas in flat terrain favorable for measuring faint radio waves. Anyone planning to visit should check access arrangements and opening times beforehand.

The telescope works together with an identical counterpart at Bear Lakes near Moscow. The two installations form a powerful interferometer for precise measurements of cosmic signals.
