Detailed View of a Solar Eclipse Corona
http://apod.nasa.gov/apod/ap100316.html
This is a picture of the Sun's corona during the 2008 total solar eclipse. The corona is normally not visible because of the brighter photosphere. Solar prominences and complex layers of gas in changing magnetic fields can be easily seen in this picture. The corona extends millions of kilometers into space. It is nearly 200 times hotter than the photosphere but is significantly less dense. It is not completely clear why the corona is so much hotter than the solar surface.
