Important notice about STEREO Behind
The Sun?s edge blossomed with all sorts of loops and arcs reaching out from a pair of active regions (April 8, 2013). The image was taken by STEREO?s (Ahead) spacecraft in extreme UV light. The loops are plasma at temperatures up to a million degrees C., contained by magnetic fields.
