The Sun’s seemingly peaceful regions are hiding a surprisingly complex magnetic world. Using a balloon-borne telescope high above Earth, scientists discovered delicate, thread-like magnetic structures woven through the solar atmosphere, apparently shaped by twisting motions on the Sun’s surface. They also mapped magnetic fields inside towering jets of solar material, revealing how those fields change with height.
