Solar switchback (animated GIF) (IMAGE) NASA/Goddard Space Flight Center Caption During its first solar flyby in November 2018, NASA's Parker Solar Probe observed switchbacks -- sudden reversals in the magnetic field of the solar wind, illustrated here. Newly-observed solar plumelets might produce similar signatures to switchbacks.
