Layers of armor protect Earth from the sun's harmful energies, while letting in heat and light that power the climate.
As an active region on the sun's surface rotated into view, Solar Dynamics Observatory captured this profile of the constantly changing magnetic field lines arcing high above it.
The sun blasted off a number of coronal mass ejections in just over two days in this image captured by the Solar and Heliospheric Observatory (SOHO) C2 coronograph.
Two dark coronal "holes" -- areas where the solar surface is cooler and less dense than average -- blossomed on the sun as the Solar Dynamics Observatory watched.
