The Sun's edge looks like a fuzzy fringe: thin jets of hot gas, spicules, shoot upward from it. They live only a few minutes and are constantly changing. In 2024, a balloon-borne telescope managed to spot not only the jets themselves but also their faint glow in hydrogen lines that had never been captured there before.

The Sun has quiet regions where the magnetic field is barely visible. But even there, sound waves find loopholes to rise higher. These loopholes are magnetic tubes that expand upward like funnels. Inside them, sound travels more freely.
