Why the Sun is Still One of the Greatest Mysteries

Date:

The sun is the closest star to us, the second closest is 250,000 times further away. So you would think that the sun has been well researched, but far from it! Natural scientist and author Christian Mähr has taken on the so-called corona paradox – and no, it is not about vaccination.

I remember a passing remark my professor made in an astronomy lecture over forty years ago: The paradox of the solar corona was still a problem, they said. This is the outermost part of the sun’s atmosphere that is visible only to the naked eye during a total solar eclipse: a beautiful halo much larger than the solar disk itself.

The paradox mentioned is their temperature, which can be measured from Earth: two million degrees. It is tempting to say: so what? Two million degrees is a common size for stars; the core of the sun is about ten million degrees. Yes, yes, but the surface, the glowing part that gives us light and heat, it is only about six thousand degrees. So the outer atmosphere of the sun is three hundred times hotter than the surface. How can that be?
