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]

In 2023, #NASAWebb peered at a portion of the Horsehead Nebula. With Webb’s near-infrared view, scientists gathered details about the “mane’s” gas and dust at the molecular level. Hydrogen, methane, and water ice compose the mane: https://go.nasa.gov/47juzZG 🔭

Actually, thinking about it a bit, I think I might have been metering with the ND filter removed, and then manually adjusting the aperture and stuff by ten f-stops to account for when I put the ND filter back on.
One aesthetic thing about a wide aperture is: no diffraction spikes on bright lights.

For stuff that's mostly the same brightness, the diffraction just makes things blurry. For one really really really really small bright point light source, you can easily see the actual shape of that blur function for a single point. And that blur is shaped like your pentagonal (or whatever) iris.

Crazy feather structure. ☺️
What we wanna see is moire patterns forming here. Maybe even those rainbow diffraction effects.
There you go that's a project!

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...

#PPOD: Jupiter and its icy moon Europa appear in this remarkable infrared image captured by NASA's JWST during its commissioning period in 2022. Observed with the telescope's NIRCam, the giant planet reveals its familiar cloud bands and Great Red Spot, while Europa shines nearby. 🧪 🔭

I'll turn it around. If you point a pinhole camera at the sun, it's hard to avoid getting a shot like this. At heart, it's the diffraction pattern caused by a stream of bright light coming through the tiny pinhole. More coming in the next couple days.
