"Solar Orbiter Unveils the Power Source of the Sun's Mysterious Wind"

The Solar Orbiter spacecraft has observed small-scale jets of energy, known as picojets, emerging from dark holes in the sun's outer atmosphere for the first time. These picojets could be the source of energy and matter for solar winds, which are high-speed outflows of hot gas from the sun. The picojets were observed in extreme ultraviolet images and are the smallest and weakest type of jets in the solar corona. The team believes that magnetic reconnection, the breaking and reconnecting of magnetic field lines, is driving these picojets. The discovery could help solve the mystery of why the sun's outer atmosphere is hotter than its surface.
