The Secret of the Sun's Heated Atmosphere

eldavojohn writes "There has long been speculation on why the Sun's surface is a mere ten thousand degrees while the atmosphere can reach millions. Space.com is reporting that the mystery has now been solved. Researchers looked for Alfven waves in the solar chromosphere and found them. Followup studies employing simulations demonstrated that the energetics work out to transfer energy from the Sun's surface to its overlying corona.. The magnetic waves may also be the power source behind the solar wind."

Joseph Preistley is turning in his grave!

I'm not familiar with Alfven, but I offer the following:

Joseph Preistley is credited with discovering oxygen.
That's a wonderful honor and all except his opinion was that air gets clogged with "phlogiston" when material is burned, such that a fire within an enclosed environment gets extinguished because the air can no longer absorb this stuff.
Nowadays, chemists understand that free oxygen gets depleted during a fire - which is the EXACT OPPOSITE of Preistley's strongly held belief.

What can I say, "misplaced honor happens".
