Global maps of the magnetic field in the solar corona ...

The solar corona is the outermost layer of the Sun''s atmosphere, consisting of hot, diffuse, and highly ionized plasma. The magnetic field in this region is expected to drive many of its physical properties but has been difficult to measure with observations. Yang et al. used nearinfrared imaging spectroscopy to determine the electron density and magnetohydrodynamic wave speed in the corona.
