Description
Summary:Dwivedi and Phillips discuss the current scientific research on the sun's outer layers, known as the corona. The sun's surface is actually much cooler than either the core or the corona, a fact which previously baffled scientists. However, due to the properties of magnetic fields existing on the surface, scientists may have discovered some possible explanations for this strange phenomenon.
