Astrophysicist’s 2004 Theory Confirmed: Why the Sun’s Composition Varies

The solar corona viewed in white light during the total solar eclipse on Aug. 21, 2017 from Mitchell, Oregon. The moon blocks out the central part of the Sun, allowing the tenuous outer regions to be seen in full detail.

About 17 years ago, J. Martin Laming, an astrophysicist at the U.S. Naval Research Laboratory, theorized why the chemical composition of the Sun’s tenuous outermost layer differs from that lower down...
