An incredible, record-resolution image of a solar flare captured in the H-alpha line (wavelength 656.28 nm) by the Daniel K. Inouye Solar Telescope.
The image shows dark coronal loops during the decay phase of an X1.3-class flare. Coronal loops are arcs of plasma that follow the Sun's magnetic field lines. They often precede solar flares, which occur when magnetic field lines twist and snap, releasing vast amounts of energy. This energy release fuels solar storms that can impact Earth's critical infrastructure. The side of the image spans approximately four Earth diameters.
