This is one of the highest-resolution images ever taken of the solar corona, or outer atmosphere. It was captured by NASA's High Resolution Coronal Imager (Hi-C) in the ultraviolet wavelength of 19.3 nanometers. NASA

Now we know where the global warming came from!
A while back people got all crazy about magnets as a cure for all sorts of diseases and conditions.
Now that fad has pretty much passed into history's dust bin.
More Magnets = Global Warming
Fewer magnets = Global Climate Stabilization

Great. Now I’ll have nightmares about drinking lemonade and getting my face burned off.
No more ice in the Jim Beam and Coke. Has anyone told the FDA about this flamethrower ice? I blame it on the Danes.

I took astronomy back in college. ALL was new and marvelous then.
It doesn't take long to get out of the loop--about ten minutes!
This adds another dimension to the song, "How Great Thou Art," doesn't it?

At the very low pressures in the corona it is not clear exactly what the term “temperature” means. There are several different ways to define the term and they give very different results.

I’m not alone in having to use a standard denial?
Hooray!

What other ways of defining it are there other than mean kinetic energy of the gas molecules (relative to one another)? Internal excitation? Furthermore, how different are the results? The corona was discovered (by an amateur) at radio frequencies, so at least the RF temperature measurement agrees with however T is being measured today. Please explain your post.

It’s a fair point but remember this is not a part of the universe in thermal equilibrium, so strictly speaking there is no actual temperature in this region, only an average temperature. It’s possible to measure that via ionization emission spectra, and that average is pretty well established.
