Jewels of the universe.
 
Coronal loops are arcs of hot plasma that rise from the Sun's surface, shaped by the Sun's magnetic field. These glowing loops, visible during solar eclipses, form part of the Sun’s corona—the crown-like outermost layer of its atmosphere. The study of coronal loops is essential for understanding solar activity, including solar flares and coronal mass ejections, which can have significant impacts on space weather and communication systems on Earth.
