The summer science school of modern astrophysics was held between July 15--26, 2014, in Zelenogorsk, near Saint Petersburg.

Forty young scientists from Russia, Armenia, Vietnam, Italy, Finland, Germany, India, Turkey, and Uzbekistan participated in the school. They were all selected by the organizing committee on a competitive basis.

The Dynasty Foundation, Moscow Institute of Physics and Technology, and the RAS Scientific Council on Astronomy organized the school.
