Man, it says each of those cells is 30k km, imagine how quickly the plasma most be moving in there for the effects you see to happen.

It's crazy how big it is.

That image covers an area 2.5x the size of Earth, but it's showing less than 0.1% of the Sun.

Does that mean that the material within those structures is moving at supersonic speeds? The video makes it look almost serene.
I wonder what the speed of sound is in the solar medium, at the ambient temperature and pressure.

About 7000 m/s on the surface.

It says each cell is the size of France. The resolution of the scope is 30km.
Yeah but how many Libraries of Congress is France across?
I want to know how many american football fields long it is, and how many olympic-sized swimming pools all that plasma would fill up.

Also, how many Hiroshimas of energy is emitted, and what is the CO2 equivalent in terms of global warming?
Lots and... Lots.
The article I read said each cell was the size of Texas. Which is it?
Certain that is the case, but is it necessarily in real time?

The same video is uncropped on nso.edu and shows a timestamp. Looks like it's sped up about 100x.
