These disks are wildly different in size and shape: some contain bright rings, some dark rings, and some even resemble hamburgers.

I see they are still banging on about accretion disks, even though the name is not used - do they not realise that this is falsified, and all models of how Planets are formed are wrong?

That took precisely 10 seconds for those to be found, and the list goes on & on (kinda like I do)

Thanks.
But it seems to me that the images have been digitally "enhanced".
Any idea where I can find the original images?

Might have to buy one of the two articles promoed in the article. Yes, they are digitally created.

I wonder what is the scale of these images, and what wavelength. They also don't seem to support anything mainstream. Dust indeed.
interstellar filaments conducted electricity having currents as high as 10 thousand billion amperes

Infrared Integral Field Spectrograph - IFS
The SPHERE integral field spectrograph (IFS) is a lenslet-based integral field unit (called BIGRE, Antichi et al. 2009), providing a 1.73” x 1.73” FOV that is Nyquist sampled at 0.95 µm. The IFS includes a flat calibration source and filters for accurate detector calibrations. The IFS instrument layout is displayed in Figure 4. The raw data 21000 spectra are aligned with the detector columns over a hexagonal grid rotated by ~10.7° with respect to the dispersion. Each spectrum from a spaxel is projected on a rectangular area of 5.1x41 pixels on the detector.
During data reduction, the image is translated into a (x,y,λ) data cube, which has for both available spectral resolutions a constant dimension of (291,291,38). Each image is resampled by the pipeline over a square regular grid at (7.4 mas)2 / spaxel. Data outside this region are meaningless.


Nyquist sampling / Fourier Transform - Capturing images

In order to get images into a form computers can manipulate they must be modified from their analog form (continuous gradients) into a digital form (step gradients) using the technique of sampling.
Sampling: A technique used to record analog information by recording periodic snapshots. If the sampling rate is fast enough, the eye cannot discern the gaps between each snapshot when they are played back. This is the principle behind motion pictures. Sampling is the key technique used to digitize analog information such as sound, photographs, and images.

A SPHERE image looks like this:
Image
- a picture for ants.

This was the first image, look like splash damage.

The ring is said to be a dust ring, i think it is a dusty plasma ring and ionized to a degree.

Dan, You know that image has been digitally pixel-multiplexed, frequency saturated and selectively contrasted,
at least...

Yes, and fracked by Hamiltonians :D

Still, it is observational data.... the only difficulty is a correct interpretation... probably everything we can think off will be proven wrong 100 years from now...or sooner...

What mainstream sees as an accretion disk, the Electric Universe sees as an expulsion disk.
