Helioseismic measurements aboard SoHO deliver new facts useful to improve our understanding of Sun and stars. After more than a decade of measurements aboard SoHO, we present the helioseismic results obtained with the GOLF instrument. If the first published papers of this community have mainly contrained the internal microphysics, these last 5 years have revealed an unprecedent insight on the impact of the solar cycle on the outer layers thanks to acoustic modes and on the radiative zone dynamics thanks to gravity mode studies. We will show why GOLF appears as an excellent instrument for this purpose and what we have learned from 10 years of observation aboard SoHO with this french-spanish resonant spectrometer. The progress done today by Doppler velocity measurements aboard SoHO (GOLF+ MDI) and by ground networks (BiSON and GONG) opens a totally new perspective for solar and stellar physics. So we then mention the questions that might be solved with the next generation of instruments already in construction in different european laboratories including GOLF-NG. They lead to two formation flying missions DynaMICCS and HIRISE proposed in the framework of the ESA Cosmic Vision perspective. An european strategy of measurements is suggested to maintain this discipline in the best conditions for the two next decades in order to get quantitative estimate of the effective role of the solar variabilities along time.
