photospheres

Stars' visible layers

Photospheres is the plural of photosphere, the visible surface layer of a star—the region that emits light we can see.

The sun's photosphere is what we observe as its disk, appearing sharply defined despite being gaseous.

Scientists study photospheres to understand stellar temperatures and activity.

The term applies to any star's luminous outer layer.
