Question

Explain why the sun’s corona can be seen during an eclipse but not at other times

Answer 1

The corona the outer layer of Sun is not visible during day time because bright sun. We can not see stars during day time. This is because during the normal daytime, the photosphere's bright light outshines the corona, like it does the chromosphere, but telescopes specially designed to take photographs of the inner corona, calledcoronagraphs, can block out the light of the photosphere and help astronomers study its properties a bit.
