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.

Looks like the video is about 20 minutes of real time per 1 second of video. There are dops of plasma that fall further than the diameter of Earth in less than one in video second... which means the plasma is falling the more than the diameter of Earth in less than 20 minutes. That's close to 100,000 mph or 160,000 kph. Dang

About 0.01% of the speed of light. I got a Lorentz factor of 1.00000001 so not quite fast enough for relativistic stuff.

The "earth to scale" really boggles my mind 🫨

Thank you, I didn't even see that.

It's there, you just gotta zoom in a bit.

God damned KDE devs at it again /s

For comparison the distance from the plasma cloud to the sun's surface is about how far communication satellites in geostationary orbit are above Earth.

I know all kinds of nerdy things.

[–] 1luv8008135@lemmy.world 4 points 5 months ago (3 children)

So dumb question, but what’s causing the gap between the plasma cloud(?) and the surface? And is that gap filled with something that is invisible?

[–] crapwittyname@lemm.ee 5 points 5 months ago (2 children)

Plasma is electrically charged, so it interacts with magnetic lines.
The sun has magnetic field lines just as the earth does. It also rotates. But- since it's not solid, it doesn't have to rotate all at the same speed. The plasma in fast-rotating regions drags the field lines further than the plasma in slow rotating areas, creating weird loops, breaks and reconnections in the field lines. I'm almost certain that what we're seeing in this lovely bit of photography is a cloud of plasma travelling across, or trapped by one of those rogue field lines which has been pushed upwards from the surface by differential rotation.

[–] 1luv8008135@lemmy.world 1 points 5 months ago

That’s fascinating. Thank you for sharing!

Nuh-uh, come on, that can't be real. So cool.

[–] crapwittyname@lemm.ee 3 points 5 months ago* (last edited 5 months ago) (1 children)

Even cooler: solar flares and mass ejections come about when one of the lines snaps like a whip and hurls billions of tonnes of plasma into space. Search: solar magnetic reconnection.

[–] dependencyinjection@discuss.tchncs.de 0 points 5 months ago (1 children)

I see words in this thread but don’t understand, but are you saying here that those streams / clouds are taught? In order to be snapped.

[–] crapwittyname@lemm.ee 1 points 5 months ago

Yes, the material the streams are made of is magnetic, and there is a strong and unusual magnetic field around the sun. So those streams are trapped by magnetism.

That gap is actually magnetic field lines suspending the plasma above the surface - its like the plasma is "riding" along magnetic highways in the sun's atmosphere, and the space between isnt empty but filled with less dense solar atmosphere thats invisible at this wavelenght.

[–] niktemadur@lemmy.world 1 points 5 months ago (1 children)

The dynamics there due to sheer gravity, magnetism and levels of energy/radiation that are utterly alien to our daily experience.

[–] NikkiDimes@lemmy.world 1 points 5 months ago (1 children)

I get some of the basic underlying mechanics, but I absolutely cannot comprehend it. Incredible.

All that energy and here we are burning oil like cavemen in the dark.

[–] GenosseFlosse@feddit.org 1 points 5 months ago (1 children)

Caveman didn't burn oil πŸ€“

[–] Schmoo@slrpnk.net 1 points 5 months ago

They might have soaked fabric or some other material in animal fat (which is just oil that's solid at room temperature), wrapped it around the end of a stick, and lit it on fire. πŸ€“πŸ€“

[–] BaroqueInMind@lemmy.one 1 points 5 months ago (2 children)

You know any efficient way to harness that energy?

[–] Someonelol@lemmy.dbzer0.com 1 points 5 months ago

Solar panels?

Doesn’t take a genius: Dyson Sphere

Dyson Sphere

I assume that's sarcasm πŸ˜‚

[–] Flemmy@lemm.ee 0 points 5 months ago (1 children)

Roughly you need at least 906.000 kmΒ² of 1x1m solar panelling.

As soon as I read the word "Scotland", my brain went back and revised this to be read in Scott Manley's voice.

[–] nailbar@sopuli.xyz 1 points 5 months ago

Thanks, now mine did too

[–] gcheliotis@lemmy.world 2 points 5 months ago

Absolutely amazing that you could capture that with β€œamateur” equipment, although it is clear from your post that a lot went into this. Bravo!

[–] trotfox@lemmy.world 1 points 5 months ago

It's crazy this guy is just doing this on his own. Looks like something from NASA to me.

fuckin love the fediverse

This image is cool as fuck. No! Wait. This image is hot as fuck.

Is this the actual image your camera sees? Or is it more like heat sensors visualized, or something like that?

[–] lurker2718@lemmings.world 2 points 5 months ago* (last edited 5 months ago)

To add what the others said, this image is most likely taken with a special filter for taking only one specific wavelength, so color. In this case H-alpha, so excited hydrogen atoms, which is deep red. With this and additional filters for safety you can see more or less this image yourself, except it's red. I already had the opportunity to try this.

Here is a site showing daily images of the sun taken with different filters. Red is H-alpha, also shown in OP. Only with this filter you can see the protuberances. White is white, so what you would see if you could look directly without burning your eyes, or what you see with eclipse goggles. Right is another special Line, Calcium K. All of this you can look at with the right filters and a telescope and it looks similar to the images here, except the two colors are even more saturated than shown here. However, changes are on the order of minutes, so it looks more like an still image.

However, the sun and planets are pretty much the only object where images are similar to what you could see with telescope and filters. Colorful images of the moon are always heavily processed. For nebulas and galaxies its even more of a difference, they are just too dark to see more than a grey blob. For this a telescope does not help much, similar to a lens not helping to see in the dark. So nebulas and galaxies are shown at least hat they would look like, if they were brighter. But most of the time they are shown with a lot brighter colors than reality.

Look at this and tell me life couldn't evolve on the Sun, that is a stable structure with reputation patterns, this alone is enough to make Conway's game of Life
