NASA’s Solar Dynamics Laboratory catches loops of light on the Sun’s surface: Cascades of spiraling magnetic loops observed in extreme ultraviolet light by SDO danced and twisted above an active region. These loops are charged particles spinning along the magnetic field lines, and thus visually revealing them. Found at YouTube from LittleSDOHMI.

New computer simulations reveal supernovae exploding in 3-D. A team led by researchers at Princeton University developed the simulations, which are based on the idea that the collapsing star itself is not sphere-like, but distinctly asymmetrical and affected by a host of instabilities in the volatile mix surrounding its core.
