Excerpt: A corona is a type of plasma "atmosphere" of the Sun or other celestial body, extending millions of kilometers into space, most easily seen during a total solar eclipse, but also observable in a coronagraph. The Latin root of the word corona means crown. During a total solar eclipse, the solar corona can be seen with the naked eye.The high temperature of the corona gives it unusual spectral features, which led some to suggest, in the 19th century, that it contained a previously unknown element, "coronium." These spectral features have since been traced to highly ionized Iron (Fe-XIV) which indicates a plasma temperature in excess of 10 k...
