Visualisation of the Sun's magnetic skeleton

This image reveals the magnetic structure that shapes the Sun's corona. While the corona appears during an eclipse as bright streamers and rays extending out into space, these features are guided by the Sun's magnetic field.

The coloured structures highlight regions where the magnetic field changes most rapidly, outlining the large-scale architecture of the corona. Warmer colours indicate structures closer to the Sun, while cooler blue tones trace features that extend farther into space.

Created using the Qorona visualisation tool and KU Leuven's COCONUT coronal model, the image provides a glimpse of the magnetic framework underlying the corona. By revealing the structures that help shape streamers and rays, visualisations like this help scientists better understand the Sun's dynamic atmosphere and improve models of space weather.
