The Solar Corona (IMAGE) NASA/Goddard Space Flight Center Caption Most of what we know about the corona is deeply rooted in the history of total solar eclipses. Parker Solar Probe will fly through this very region, seeking clues to the Sun's behavior. This photo was taken in Madras, Oregon, during the total solar eclipse on Aug. 21, 2017.
