astrophysics is really making some remarkable leaps this decade ("Max Planck Institute for Solar System Research" sounds so wonderfully Star Trek doesn't it)

    heh, well, 275 years ago Benjamin Franklin was messing around with something he didn't truly understand but named a "battery" and three centuries later we are launching and parking multiple spacecraft with super-telescopes in L2

In the abstract, they're stating that the magnetic field of the sun is what's causing the surface to look as if it's wind-swept -- is that right? Am I reading that correctly? So the extensive shifting of the magnetic field is causing the visual distortion?

Figure 1c from the paper[1] looked like it would make a great desktop background, but the resolution on the web is mediocre and there is this dashed rectangle to indicate the extent of the d-f subimages. In the PDF, the rectangle is drawn on top as a separate object so you can easily extract the underlying object! Here are the figure 1 a-c images, lossless as they are in the PDF, having cropped a few transparent pixels for each one: https://lucgommans.nl/tmp/doi_10.1038_s41586-026-10871-3_figure1a.png https://lucgommans.nl/tmp/doi_10.1038_s41586-026-10871-3_fig... https://lucgommans.nl/tmp/doi_10.1038_s41586-026-10871-3_figure1b.png https://lucgommans.nl/tmp/doi_10.1038_s41586-026-10871-3_fig... https://lucgommans.nl/tmp/doi_10.1038_s41586-026-10871-3_figure1c.png https://lucgommans.nl/tmp/doi_10.1038_s41586-026-10871-3_fig... edit: supplementary video 2 has a panel similar to figure 1b in 10% higher resolution, screenshot: https://lucgommans.nl/tmp/doi_10.1038_s41586-026-10871-3_supplementary-video-2_crop.png https://lucgommans.nl/tmp/doi_10.1038_s41586-026-10871-3_sup...
