Corona

Explanation:

The outermost layer of the sun's atmosphere is called the corona, meaning “crown.” The corona is formed of thin wisps of gas that extend outward into space for millions of miles. It is much less bright than the photosphere, so we can only see it if the rest of the sun is blotted out, for example during a solar eclipse.
