This region is notoriously tricky to study because one can't easily track the way light moves through it. It is filled with plasma, whose movements are governed by the tangle of magnetic fields surrounding the sun.
While the sun's surface is 6000K, the corona can reach up to millions of degrees, sparking questions from researchers on what mechanisms heat the atmosphere so dramatically.
The word Science comes from Latin word "scientia" meaning "knowledge" and in the broadest sense it is any systematic knowledge-base or prescriptive practice capable of resulting in prediction.
Science can also be understood as a highly skilled technique or practice.
You can use it freely (with some kind of link), and we're also okay with people reprinting in publications like books, blogs, newsletters, course-material, papers, wikipedia and presentations (with clear attribution).
The relatively thin region – five to ten thousand miles tall -- of the solar atmosphere located above the sun's surface.
Scientists make observations of natural phenomenon and then through experimentation they try to simulate natural events under controlled conditions.
Based on observations, a scientist may generate a model and then attempt to describe or depict the phenomenon in terms of mathematical or logical representation.
Most scientific investigations use some form of the scientific method.
The scientific method tries to explain the events of nature in a reproducible way, eventually allowing researchers to formulate testable predictions.
