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).

100 Russian rubles issued in 2015, printed to commemorate the Crimean spring

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, i.e. the multiple Cosmic Calls, Teen Age Messages or AMFE. Radio telescopes are highly sensitive detectors of signals from outer space.

Since the 2014 Crimean crisis, the status of Crimea, and thus of the city of Yevpatoria which is located on Crimea, is under dispute between Russia and Ukraine; Ukraine and the majority of the international community considers Crimea and Yevpatoria an integral part of Ukraine, while Russia, on the other hand, considers Crimea and Yevpatoria an integral part of Russia.[1] The radiotelescope is depicted on Russia's 100 ruble banknote.[2]

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:
