The main goal of RACIO is to providing free access to modern observational facilities and e-infrastructure, available or planed; by improving the working conditions and attracting new researches; by facilitating and organizing astronomical training schools and workshops for young astronomers, students and PhD students and by supporting scientific collaboration in joint projects and observational programs with astronomers throughout the EU.
