I analyze #JWST data using code, with some manual adjustments such as co-registration of misaligned filters, and choosing whether to use log scale or not. My code is on GitHub. Here are some peeks. Below is a 100% automatic preview of NGC objects (mostly).

#JWST 🔭 NIRCam data for NGC-2440
A planetary nebula, a dying star shedding material
NASA, ESA, CSA, STScI
chatGPT: Infrared image of the planetary nebula NGC 2440, showing a brilliant, chaotic structure surrounding a dying star at its center. Twin lobes of gas and dust expand outward in a butterfly-like shape, glowing in shades of red, green, and violet. The star’s intense light radiates through the nebula’s translucent filaments, revealing layered shells of ejected material. Surrounding the nebula, a dense field of golden and white stars fills the background, scattered across the dark expanse of space.

technical: #JWST 🔭 data comes in .fits files with 10 objects, where only the first (header) and second (data) are useful for me. While it is easy to download the header with fitsheader, it is tricky to download the data itself.
I use astropy with use_fsspec to do that but sometimes it fills RAM, >

V* V2455 Ori outflows in rings. Take this in different IR hues that #JWST 🔭 gives us, and you get a candidate for the most beautiful corners of our galaxy.
chatGPT: A vivid infrared view of the star-forming region HOPS-108. At the center, a brilliant yellow-white newborn star shines with intense diffraction spikes, surrounded by glowing clouds of gas and dust. Wisps of purple, blue, and orange flow outward in curved arcs, tracing powerful jets of material ejected from the young star. The surrounding nebula glows in iridescent layers, with cooler blue regions blending into warmer gold and magenta tones. Numerous smaller stars sparkle across the frame against a deep, cosmic blue background.

Complete image of the planetary nebula NGC 2440.

Green is molecular hydrogen (F212N), blue is iron emission (F164N) and red is emission by hydrogen atoms (F405N). Orange for the F356W filter.

A green circular nebula and a violet bi-polar nebula (vertical) within this circular nebula. Two long yellow structures (probably jets) are present at a 45° angle within the bi-polar nebula (towards bottom left and upper right). In the background are stars and galaxies.
