The explanation of dark energy requires extending General Relativity. A striking prediction of general theories in this regard is that the gravitational law is modified within compact astrophysical objects, through a fifth-force effect. Here, we proposed helioseismology as a novel precision probe of the fifth force at local scales. With the aid of helioseismic simulations, we showed how the observed frequencies of solar pulsations can significantly improve previous constraints on the fifth-force strength, in turn providing invaluable new insights for the nature of dark energy.
