Data from space probes show that Alfvén waves drive the acceleration and heating of the solar wind
NASA’s Parker Solar Probe and ESA’s Solar Orbiter missions measuring the same stream of plasma flowing away from the sun at different distances. Parker measured copious magnetic waves near the edge of the corona (the “Alfvén surface”), while Solar Orbiter, located past the orbit of Venus, observed that the waves had disappeared and that their
