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 scientific literature, it is often called the Evpatoria Planetary Radar (EPR).

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[ which? ] in the world that are able to transmit messages to extraterrestrial civilizations,[ citation needed ] 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. [1]

In August 2025, the main dish of the telescope was hit by a Ukrainian drone as part of the Russo-Ukrainian War. [2] [3]

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

In 1999, 2001, 2003, and 2008, for the transmission of messages to extraterrestrial civilizations:
