A Hidden Art
This composite image is a visual representation of a fictional sun â one that is a cumulative amalgamation of solar activity for the past 17 years. Using 250 images collected by the Solar & Heliospheric Observatory and Solar Dynamics Observatory spacecraft, the visualisation shows the numerous and highly varied forms of plasma structures that occur along a series of closely occurring loops of magnetic lines of force. Plasma is a state of matter consisting primarily of electrons and positively charged protons whoâs fluid form is dictated by the constantly shifting magnetic fields on the surface of the solar corona. The most prominent flares and eruptions occur with the rearrangement of magnetic field lines when two oppositely directed magnetic fields are brought together. These ejections stream out into interstellar space and reach the earth resulting in dramatic geomagnetic storms.
