Another cloud free day in Scotland let me catch almost 9 hours of this huge and lively prom. Taken with my home made 90mm modded Coronado PST and DMK21 camera. Software: CdC, Eqmod, DSSR, AutoStakkert!, Wavesharp, DVS, Shotcut and Gimp.

Thought "that's pretty neat", and then noticed the "earth to scale" part. Holy shit. Those are streams of plasma larger than continents.

thank christ I read this and went back, that's lightly humbling for real

Made me think of this song by They Might Be Giants (which apparently isn’t their only song about the sun lol) https://m.youtube.com/watch?v=3JdWlSF195Y

The "Earth to Scale" in the top left corner is terrifying...

Soooo incredibly beautiful. I love how it waves around, and the scale of it is just awesome. It's crazy that some of those oscillations are fast enough that, if overlaid with the earth, would be absolutely flying across the sky in real time. But by far the most interesting part is how the cloud structure just hangs there while bits of it get torn off and dragged into the surface, and the way it has almost a surface tension like effect even at that size. It really doesn't look much different from water on the window during rain. Does anyone know why or how the cloud stays suspended like that while the bits get torn off? At that proximity, naively, I would have thought gravity would just pull the whole cloud in, especially if it's strong enough to pull the bits in?

I'm pretty sure it's suspended by a magnetic field, just like were trying to do with our fusion reactors. Could be wrong though.

This has a good visualization of how turbulent the suns magnetic fields are after watching how they move this suspension in a magnetic field makes more sense to me. (If that's what's happening I am not an astrophysicist)

The scale is mindblowing.

That's the coolest lava lamp I've seen yet

Why don’t we just go to the sun and put some of that in a tokamak?
