What you’ll discover
- The Sun’s inverted temperature profile
- Why sunspots look dark
- The competing magnetic-heating pathways
Show notes
The photosphere is where visible light escapes, not the outer edge of solar energy. Above it, the thin corona can reach temperatures far higher than the surface below.
No single slogan settles the coronal-heating problem. Waves can carry energy upward; countless small reconnection events can release stored magnetic energy; observations suggest the balance varies across solar structures.
Key facts and named entities
- Photosphere: about 5,800 K
- Corona: often above 1 million K
- Candidate: wave heating
- Candidate: magnetic reconnection
