Sometimes, during a total solar eclipse, the corona of sun is visible to our eyes.

No single eclipse ... solar or lunar ... is ever visible from every place on earth.No single solar eclipse is ever visible from every place or even half of the earth.

corona
During a complete solar eclipse (In which neither the sun or moon is visible) the moon is in front of the sun, blocking its light from the earth.
During a solar eclipse, the shadow falls on Earth as the Moon blocks the Sun's light from reaching specific areas. This creates a temporary darkening of the sky and can be observed from the regions where the eclipse is visible.
Energy radiated from the surface of the sun visible during a solar eclipse appears in the form of the corona, which is the outer atmosphere of the sun. This is a faint, glowing halo of plasma that extends millions of kilometers into space and is only visible during a total solar eclipse when the moon blocks the brighter light from the sun's surface.
The ring visible as the moon passes in front of the sun during a solar eclipse is called the corona. This appears durian a total solar eclipse, when the apparent size of the moon is larger than the sun.During an annular eclipse, where the moon's apparent size is smaller than the sun, the ring visible around the moon is called the annulus.
