Last winter, The Westbrook Ice disk formed naturally over an approximately three week period in the Presumpscot River in Westbrook, Maine. It was about 100 yards wide and slowly rotated counter-clockwise.
Full solar disk captured in Ha light on 30th August with my Lunt LS152THa, and Altair Hypercam 174M cooled camera.

Fatto il 10 luglio, ne ho già voglia di altri nuovi XD sono insaziabile XD
Voodoo Girl -
Her skin is white cloth,
and she's all sewn apart
and se has many colored pins
sticking out of her heart.
She has a beautiful set
of hypno-disk eyes,
the ones that she uses
to hypnotize guys.
She has many different zombies
who are deeply un her trance.
She even has a zombie
who was originally from France.
But she knows she has a curse on her,
a curse she cannot win.
For it someone gets
too clore to her,
the pins stick farther in.

This is an accretion disk around a forming protostar. The accretion disk is like two bowls with their bottoms up against one another. It's very thin in the middle and flares out along the outer rims. For some reason which remains unknown to me, fast, collimated outflows or jets can erupt along the poles of the forming star. It's either got something to do with magnetism or something to do with the way the outer envelope falls into the star... or maybe both, or something else? Turns out I have no idea what I'm doing.
The thin, dusty envelope was the hardest thing for me to figure out how to illustrate. It's huge, everywhere, and falling down into the accreting protostar, and tends to get in our way of seeing these things because there's so much of it.
Once again, I used Blender to help me visualize the dusty cloud. A lot of painting went over the top of that to add details that are very difficult to create in a volume model with Blender.
The PSF was modeled with Tiny Tim.

Played golf (badly) with my son today and he brought over these old 3.5 inch disks. He's 21 and didn't know what they were :-) He told me he'd brought some weird CDs that mum didn't want but thought I might. These are from the mid 90s when I was doing my MSc research with semi-conductor diodes. Funny to think how these disks held just 1.44Mb data compared to the TBs you can get on small portable devices now!
There is a long list of space illustrations which bother me for a variety of reasons, and images of protoplanetary disks are a big offender. While I'm not entirely pleased with my own rendition and may try again at a later point, several key issues are addressed:
1. The star is a point source. You will never see anything but a point source at the scale of planetary disks.
2. Just as you will never see the star as anything but a point, you will also never see any planets. At most, if you were looking in the infrared, you would see another point source many orders of magnitude dimmer than the parent star. It would have its own PSF (point spread function) and that's it. Maybe I could put a dim point source in one of those empty lanes. It's possible. I'll think about it.
3. Because there are no visibly large planets, there are no shadows being cast by them. Even if you were next to a planet, you probably wouldn't see any shadows because "god ray" style shadows depicted in sci-fi movies and art require very specific conditions to occur and probably never happen in space quite like that. Larger scale shadows, sure. We have even seen those recently, but that shadow is cast by perturbations of Earth-orbit-sized structures of the disk itself, not some puny little planet.
Anyway, here are some further thoughts running through my head when illustrating this:
Looking at ALMA and Hubble imagery of real planetary disks, I find them to be astonishingly regular. There are some leftover bumps and blips in Hubble's images, but that's from the star's PSF, not necessarily part of the disk itself. So I assume they are very, very circular and smooth. Something like Saturn's rings.
Understanding basic orbital mechanics and also from studying larger scale disk objects, I guess that they are fluffier as distance from the star increases. I tried to show that. I put some texture in the diffuse foreground ridge and made sure the dust significantly reddened the light passing through it. It might still be too dense at this point, which I imagine to be around 120 AU from the star.
I also imagined an extremely tenuous spherical orb of dust which is denser near the star and virtually nonexistent farther out. You can see it peeking out from under the foreground dust ring. The idea here is that even though this disk is regular now, in the past it had a tumultuous beginning before the angular momentum of the matter swirling around the star settled into its average position like this. Over millions of years this and all dust is dragged into the star, but before that happens, maybe a little is leftover to slowly spiral inward. Just an idea. Possibly totally wrong.
I used Hubble's PSF for the star. I'm a fan. So what. If you noticed that before reading this, then count yourself as either very experienced with Hubble or very perceptive. The PSF was modeled with Tiny Tim.
.... In with new.
And hopefully out with my old attitude, and in with the new, improved one of wanting to shoot.

Forex Apocalypse was created by Michael Wright and his team at FX Trading Bots. At the website, there is a video created by Andrew West, who is the head of the development and testing team at FX Trading Bots, which explains what this revolutionary new trading robot can do.
What makes forex robots, or expert advisors, like the Forex Apocalypse so attractive to forex traders or potential forex traders is that they do not require any attention from the user as everything is done on autopilot. In addition, the user does not have to know anything about forex or how to trade forex. This allows users to get setup and trading in a matter of minutes without any learning curve.
This wheat field was recently harvested and the straw baled and stacked in the field. The tractor and disk are parked since summer rains have made the field to wet to work.
