There are two main observatories operating in Badary:

The Badary Radio Astronomical Observatory (BdRAO) was founded by the Institute of Applied Astronomy (IAA) as one of three stations of the Russian VLBI network QUASAR. The sponsoring organization of the project is the Russian Academy of Sciences (RAS). The Badary Radio Astronomical Observatory is situated in the Burytia Republic (East Siberia) about 130 km east of Baikal Lake. The basic instruments of the observatory are a 32-m radio telescope and technical systems for making VLBI observations. The three observatories Badary, Svetloe, and Zelenchukskaya make up the stationary “Quasar” VLBI network.

The Siberian Solar Radio Telescope (SSRT, operated by the Institute of Solar-Terrestrial Physics) is located about 2km south-west of BdRAO and is a special-purpose solar radio telescope designed for studying solar activity in the microwave range (5.7 GHz) where the processes occuring in the solar corona are accessible to observation over the entire solar disk. SSRT sensitivity is such that it is possible to observe active regions at all stages of their development, at the background of the emission of an undisturbed solar atmosphere. SSRT is a crossed interferometer, consisting of two arrays of 128×128 parabolic antennas 2.5 meters in diameter each, spaced equidistantly at 4.9 meters and oriented in the E-W and N-S directions.
