Tangled Up in Blue

NASA - Solar Dynamics Observatory (SDO) patch.

May 3, 2018

The lone active region visible on our Sun put on a fine display with its tangled magnetic field lines swaying and twisting above it (Apr. 24-26, 2018) when viewed in a wavelength of extreme ultraviolet light.

The charged particles spinning along these field lines illuminate them. The region did not erupt with any significant solar storms, although it still might.
