Telescopes. The eyes and ears of man in the universe. Today it is impossible to imagine the study of outer space without these tools. In the mountains of Karachay-Cherkessia, the largest telescope in Eurasia, the Large Azimuth Telescope, has been operating at the Special Astrophysical Observatory of the Russian Academy of Sciences for forty years. Every night, scientists from different countries conduct observations of distant stars and galaxies here.
