Radio telescopes are highly sensitive detectors of signals from outer space. With its 70-meter antenna diameter, the Yevpatoria RT-70 is among the largest single-dish radio telescopes in the world. It has an advantage in comparison with other large radio telescopes in the fact that the complex includes powerful transmitters that allow active space experiments. Powerful electromagnetic beams can be accurately targeted and the signals received can be analyzed. For this reason, the Yevpatoria RT-70 radio telescope is one of only two in the world that are able to transmit
messages to extraterrestrial civilizations, e.g. the multiple
Cosmic Calls,
Teen Age Messages, or
A Message from Earth (AMFE). The radio telescope is depicted on Russia's
commemorative 100-ruble banknote of 2015. In August 2025, the main dish of the telescope was hit by a Ukrainian drone as part of the
Russo-Ukrainian War. == Missions ==
