JWST image of Arp 220, also known as IC 4553.
Arp 220 is actually two spiral galaxies in the process of merging. Their two cores are about 1,200 light-years apart. The merger sparked an enormous burst of star formation, creating a star-forming ring in each core. These two adjacent, small, bright areas are responsible for the six large diffraction spikes that dominate the image.

Spotted this great image, yes a real image, last night! It looks like a firework going off!
It's of the supernova remnant Pa 30 and was taken by the Gemini Observatory (north).
It's probably the only one of these I have ever seen an image of and could also be the only one we know about in the entire Galaxy.
Pa 30 (IRAS 00500+6713) has a central white dwarf star (eventually what our Sun will become).
The idea is that this supernova ejecta formed in 1181 and may have been observed / documented by Chinese and Japanese astronomers. It's thought to have formed when two white dwarfs collided.
Those long radial filaments are likely caused by Rayleigh- Taylor instabilities. The authors of the paper below suggest that these could be what's left over from a slower ejecta shell that has been shaped into these long, narrow structures by the winds of the white dwarf star.
The white dwarf itself is fascinating. Likely rapidly rotating and has a very powerful magnetic field (almost as strong as a millisecond pulsar).
Truly an odd, yet wonderful Galactic object!

The full sky in the ultraviolet
https://menard.pha.jhu.edu/uvmap/
"This is the whole sky in ultraviolet light — the first detailed version with no holes in it. Most of it was photographed by NASA’s GALEX space telescope between 2003 and 2013; the parts no ultraviolet telescope ever saw were filled in by a statistical model, and every such pixel is labelled. The top of this page is for anyone curious about the sky; the bottom is for astronomers who want the numbers, the files and the paper. …"
