The Yevpatoria RT-70 radio telescope (P-2500, RT-70) is an RT-70 radio telescope and planetary radar at the Center for Deep Space Communications, Yevpatoria, Crimea. In the scientific literature is often called Evpatoria Planetary Radar (EPR).

With its 70-meter antenna diameter, it 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.[citation needed] Radio telescopes are highly sensitive detectors of signals from outer space.

The radiotelescope is depicted on Russia's 100 ruble banknote.[1]

The telescope has participated in Soviet space program since 1978 for the exploration of deep space:

In 1999, 2001, 2003, 2008, transmit messages to extraterrestrial civilizations:
