corona and was
The fact that the Sun has a million-degree corona was first discovered by Gotrian in 1939 and Bengt Edlén in 1941 by identifying the coronal lines ( observed since 1869 ) as transitions from low-lying metastable levels of the ground configuration of highly ionized metals ( the green FeXIV line at 5303 Å, but also the red line FeX at 6374 Å ).

corona and by
During a total solar eclipse, the solar corona can be seen by the naked eye.
Light from the corona comes from three primary sources, which are called by different names although all of them share the same volume of space.
The sun's corona is much hotter ( by a factor of nearly 200 ) than the visible surface of the Sun: the photosphere's average temperature is 5800 kelvin compared to the corona's one to three million kelvin.
The corona is separated from the photosphere by the relatively shallow chromosphere.
The exact mechanism by which the corona is heated is still the subject of some debate, but likely possibilities include induction by the Sun's magnetic field and sonic pressure waves from below ( the latter being less probable now that coronae are known to be present in massive, hot, highly magnetic stars ).
Since the corona has been photographated at high resolution in the X-rays by the satellite Skylab in 1973, and then later by Yohkoh and the other following space instruments, it has been seen that the structure of the corona is very various and complex: different zones have been immediately classified on the coronal disc
