The corona is the region of the sun from the surface to about 1 million kilometers into space. Temperatures in the corona can reach as high as two million degree Fahrenheit.
The corona is the visible part of the Sun that we can see.
One interesting thing that has been found about the corona is that it's much hotter than the Sun's surface - while the Sun's surface has a temperature of about 6000 K, the corona has a temperature has a temperature around a million K. This obviously can't be caused by regular heat transfer; scientists are still researching exactly how the energy gets from the Sun to the corona.
