Sun's magnetic arches may be just a projection artifact, research suggests

  • The paper buried at the bottom of the article is recommended over the superficial article.

    I was balking at the term "optical illusion", and it turns out that the word "illusion" never even appears in the paper. The paper has a lot of excellent illustrations and simulation photos.

  • I'm surprised by this discovery too, I would have thought we would have been able to observe something like this with the STEREO spacecraft [0] which are pair of identical spacecraft that are imaging the sun at different angles.

  • I think this is akin to the illusion of ring nebulae, which are more like bubbles than actual rings. Because they are a gas explosion, their 3D exterior edges look thicker in 2D. So, if you are looking through a 3D cloudy sheet, it will look like a 2D “garden hose.”

  • In case anyone reading this works for Fortinet.. FYI, this domain is currently categorized as 'pornography'.

  • > sometimes be optical illusions “created by folds or wrinkles in much larger ‘sheets’ of solar material that the authors call coronal veils.”

    So we’re seeing a sheet of paper from the side?

  • Flat sun

    (The substantial introspection here is that modern flat earth fans believe that going into space and observing the earth results in an optical illusion)

    so its going to be comical when other celestial bodies have that and it emboldens flat earth proponents

  • Am I the only one who finds the tube model weirder than the sheet/veil-like model? I know it's too easy to call findings out as "obvious" after the fact, but I guess I never even realized that the 3D volumetric structure needed this clarification.

  • At what point does something with an effect so powerful cease to be an illusion and become real?
