It's the circle of life… Webb's look at the Lion Nebula, the remains of a dying lower-mass star, is in both the mid and near-infrared. Though massive stars undergo supernova explosions at the end of their lives, lower-mass stars shed their outer layers.

A paper in Nature presents the highest resolution observations of the Sun’s visible surface reported to date. The time-sequenced images provide a more complex picture of the Sun’s surface layer than previously seen, giving new insights into the magnetically active regions within this layer. πŸ”­πŸ§ͺ

Ubiquitous Kelvin–Helmholtz instabilities driving plasma mixing on the Sun - Nature

High-spatial-resolution observations of the solar photosphere reveal a far more complex and dynamic solar scene than previously observed and show that ubiquitous Kelvin–Helmholtz instabilities drive plasma mixing on the Sun.

Here is my version. I had to crop the entire image to this region. Filters: F162M (Blue) F164N (Cyan) F444W (Green) F470N (Red) Muchas gracias @landru79.bsky.social por pasarme el archivo GIMP.

Here are a few shots of the "[HRS2015] PN?" as it appears on SIMBAD database. Here I used only the f444w and f444w-f470n filters, automatic processing by code.

chatGPT: A James Webb Space Telescope NIRCam image of a candidate planetary nebula set against a dense star field. At the center is a brilliant white core, the exposed remnant of a dying star, surrounded by a glowing orange shell of gas expanding into space. The nebula has an irregular, butterfly-like shape, with broad lobes extending to the left and right and delicate, filamentary arcs radiating outward. Fainter semicircular shells curve around the central nebula, especially to the upper left and lower right, hinting at multiple episodes of mass loss. Thin rays and wisps of gas extend beyond the main shell, giving the object a textured, feathery appearance. The surrounding field is filled with sharp white stars of varying brightness, some displaying six-pointed diffraction spikes. Small, isolated brownish clouds near the upper right and faint diffuse nebulosity along the lower right edge provide additional structure, while the candidate planetary nebula dominates the scene with its bright core and intricate network of expanding gas.

Candidate background planetary nebula, described in Hartigan et al. 2015 iopscience.iop.org/article/10.1..., see figure 11 and text section 4.3 Image with #JWST NIRCam commons.wikimedia.org/wiki/File:HR...

A bi-polar planetary nebula with red clouds and a yellow inner region. Clouds from the Carina Nebula are all around the candidate planetary nebula.
