ESA and NASA's Solar Orbiter mission has traced giant magnetic switchbacks — sudden S-shaped bends in the solar wind's magnetic field — directly back to their origin near the Sun. The finding supports the idea that these switchbacks are generated in the solar surface and lower atmosphere, offering new insight into how the Sun heats its corona and accelerates the solar wind across the solar system.
