Is that our Sun? The unusual banana-shaped loops shown above are actually part of a computer-generated snap-shot of our Sun's magnetic field.

Magnetic field lines loop through the solar atmosphere and interior to form a complicated web of magnetic structures. Many of these structures are visible in the chromosphere and corona, the outermost layers of the Sun's atmosphere. Surfaces of constant magnetic field strength (like the "bananas") loop through the Sun's corona, break through the Sun's surface, and connect regions of magnetic activity such as sunspots.
