Density Map of Solar Corona |
||||||
 |
||||||
|
||||||
| A map of the Sun’s outer atmosphere, the corona, shows different densities in the layers of hot gas that surround the Sun. Blue regions indicate the highest density; yellow highlights areas of lower density. The magnetic field of the Sun interacts with gas layers to cause the strange curves, streamers, and bumps observed here. The corona consists primarily of electrons and ionized atoms heated to temperatures of approximately 2.2 million degrees C (4 million degrees F). | ||||||
