Question

Which layer do you see when you look at a typical image of the sun?

Answer 1

What we see as the "surface" of the sun is the photosphere .

Explanation:

While the "surface" of the sun looks substantial enough, it is actually a near vacuum, at about `1/6000` the density of our atmosphere at sea level. But it is like a glowing fog, so at a distance, it looks solid, the same way a cloud looks solid from a distance.
