Abstract
Solar Physics Spicules are small jets of plasma from the surface of the Sun that last a few minutes. Around a million are occurring at any moment, even during periods of low solar activity. The mechanism responsible for launching spicules remains unknown, as is their contribution to heating the solar corona. Samanta et al. observed emerging spicules and the magnetic fields in the adjacent solar surface. They found that many spicules appear a few minutes after a patch of reverse-polarity magnetic field and that the overlying corona is heated shortly afterward. This result provides evidence that magnetic reconnection can generate spicules, which then transfer energy to the corona. Science , this issue p. [890][1] [1]: /lookup/doi/10.1126/science.aaw2796
