Spectacular iridescent cloud spotted in Indonesia. A diffraction phenomenon caused by small water droplets individually scattering light. They often occur on lenticular clouds on top of a cumulonimbus, called pileus. [📹 cut_risaa]

Very proud of our team with two papers on arXiv! Shrish Ray's does JWST wavefront sensing with a differentiable optical model (arxiv.org/abs/2610.40187), and Milo Langker's shows that you can infer a spectrum from a single diffraction-limited image (arxiv.org/abs/2610.41092)!
Spectral Information Content of Diffraction-Limited Images
High-resolution optical imaging is fundamentally limited by diffraction, which imprints wavelength-dependent structure onto the point spread function (PSF) of the optical system. This intrinsic chroma...

Let’s go deeper and find the source of this PDF reference. The reference is the article with a simple title “Chemical Analysis by X-Ray Diffraction” from Dow, that contains a mistake.

Obviously, I wanted to find out that what is this unknown phase; and fortunately, now there is perfect method for such kind of mixed samples – electron diffraction. We do not have electron diffractometer (yet), so I sent the sample to Rigaku Europe.
