The corona.
The solar corona, or upper atmosphere, is only visible during a solar eclipse.
The bright light from the Sun overpowers the faint light from the stars but during a solar eclipse when the light from the Sun is block the stars and constellations become visible.
The corona is (visually) a fairly bright, hazy "halo" around the sun that can be seen during totality of a solar eclipse. It is always there, but under normal circumstances, the sun is so intensely bright that the much dimmer corona cannot be seen.
Usually, we cannot see the corona because of the brightness of the photosphere. However, during a total solar eclipse, the corona shines beautifully against the dark sky. During a partial or an annular eclipse, a ring of the photosphere is visible around the Moon and the corona is not visible.
You can see the chromosphere during a total eclipse.

The outermost layer of the sun is the corona. Only visible during eclipses, it is a low density cloud of plasma with higher transparency than the inner layers.
Sometimes, during a total solar eclipse, the corona of sun is visible to our eyes.

The solar corona, the thin sort-of-bright atmosphere of the Sun, was only visible during total solar eclipses. That's because the Sun itself was so much BRIGHTER that the corona was completely invisible except during an eclipse. With a special telescope called the coronagraph developed in 1930, it became possible to block the Sun's direct light and view the corona all the time.
