Amazing close-up video of the sun

[disappoint]

Woah that's epic. I've been thinking it would be cool to take a pic of the sun with my telephoto lens (with a ridiculously fast shutter speed) but too scared I damage the lens or camera.

Well make up your mind! Is it a wave or a particle!

Tee hee.

Doesn't that depend on whose looking at it? Or what formula you believe is true? Or what day it is?

 

[Markbnj]

Well in that case, everything on Earth came from stars. So there wouldn't be any geothermal nor tidal power without Earth and the moon both of which formed from stars erupting long ago.

Which is ultimately just the uneven distribution of matter, right? If matter was all spread out evenly in the universe (high entropy) everything would be cool.

Yes and it appears as if the uneven distribution of matter came about from increased "dark matter" which is to say increased gravitational potential in certain areas as seen in the Illustris Simulation which I know you've seen but I'm linking the thread here for others in case they haven't:

You can see there the relationship between increased dark matter and increased baryonic temperature by that I think they mean the formation of stars due to coalescing of hydrogen to the point of fusion into helium. More massive stars can fuse even helium and so on and so forth to the higher mass elements.

The question I have: Is dark matter the catalyst for the formation of stars in the first place?

 

[BUTCH1]

Yeah, we lack words. "Titanic" just doesn't seem to cover it. Those swirling jets of matter are in many cases hundreds or thousands of earth diameters across. Amazing. Even more amazing that we have a little machine out there photographing it all in detail.

Awesome, after watching it one thinks " how is that probe able to withstand the sun's rage and still work", they must have some hell of an insulation going on in that machine!..

Tee hee.

It's a wave packet..., and it looks like this:

By it I mean a photon.

As far as solar flares go, they are made of atoms, electrons and ions. So they are matter. Though they emit lots of photons, UV, X-Ray, visible and more.

 

[spidey07]

So I assume x-rays are photons as well? Any EM that the sun emits is photons, right? Along with some matter. It would be interesting to know what the different filters/imaging sensors used in the video were. It looked to be many different kinds, you can recognize the x-ray one.

I still want to know what that tornado looking vortex was.

Yes, X-rays are photons.
Wiki.

X-rays, microwaves, gamma rays, ultraviolet, visible light infrared, radio waves....all the same stuff, just different wavelengths.

And I wonder what that is made of. A little pocket of contorted spacetime? Or....????

SDO orbits Earth.

The Stereo A&B spacecraft orbit at the same distance as Earth. It's probably easier to build a really good telescope, rather than have to fly in close to the Sun. Check out online images of the MESSENGER spacecraft, which is exploring Mercury. There's a sunshield on one side, and relatively small solar panels.

So you can insulate, or use a really good mirror.

Good question. You caught me. The gif above is an oversimplification. It's a 3D (2D spacial, 1 time) representation of something that is actually 4D (3 spatial dimensions, and 1 dimension of time).

What it is really made of is pure energy in the form of an electric field and a magnetic field traveling perpendicular (90°) to each other. This is why it's called an EM or electromagnetic wave. Visible light, infrared light, UV light, X-ray, Gamma rays and radio waves are all examples of EM waves.

P.S. Contortion or warping of spacetime would cause a gravitational potential. A changing contortion of spacetime would cause gravitational waves. Very different from EM waves.

P.P.S. EM waves propagate through space and must follow the curvature of space. Gravitational waves are changes in the fabric of spacetime itself propagating along spacetime, in other words space itself moving.

There are gravitational wave observatories in several countries but they have not picked up any gravitational waves yet other than noise which they are set up to ignore. Any moving mass would create a gravitational wave so they do exist. Getting off topic in OT so I'll stop there.

Amazing it is not ? I may be wrong, but it looks there is a burst of x rays generated at 3:00.

 

[William Gaatjes]

At 2:17 you see some kind of solar tornado/vortex

Maybe there where spiraling magnetic field lines. The plasma is sort of captured, following the field lines. Then the magnetic field line "breaks" apart. Releasing the plasma.
Maybe there was a plasmoid formed.

 

[disappoint]

Well, that de-escalated quickly.

 

[Albatross]

That`s not the sun,that`s the moon.

 

[spidey07]

More science shit.

Why can't we achieve fusion? It's a massive question.

 

[NikolaeVarius]

We can achieve it just fine.

As for self-perpetuating and energy positive? Well we don't have the benefit of simply having enough mass so that gravity acts as the mechanism to fuse hydrogen.

We need to do it the crude way, which is very power intensive.

Guess you didn't catch the "massive" problem.

Cool!

"Fields" are just an interesting concept, especially since they seem to have a limit to their propagation speed. Just an inherent property of this bubble of spacetime we live in.

That does remind me of something else that comes to mind:
Matter and energy can be converted from one to another; stars convert matter to energy all the time.
So if I had an insanely powerful little pocket of energy, would it have gravity? I don't think we'd be able to measure the gravitational field of energy right now because, well, think of how much energy comes from the conversion of a single gram of matter. It's a devastating amount. Then think of how much gravity that gram of matter has.

We can achieve it just fine.

Just watch, something will come out of a discovery at a particle accelerator or advances in theoretical physics, and we'll figure out a way of generating a simple field that neutralizes the mutual repulsion between atoms. Mr. Fusion goes to market a few years later.
(We have technology now that is nothing short of impossible magic to someone living a thousand years ago.)
