A magnified portion of the green loop structure showing a series of bubble-like structures, which look like raindrops hitting a puddle. Supernova ejecta in the remnant interior? Supernova interaction with the surrounding CSM? IFU spectroscopy: - Warm dust - Low line velocities Correlates with X-ray gas with CSM abundances De Looze et al. 2023, in prep

Lot of neat stuff about JWST observations of supernovas from Tea Temim this morning, including an update on the Cassiopeia A supernova remnant observations.
What are those bubbles in the area known as the "green monster?" The team's current thinking is that in the past, dense clumps of ejecta shot through the gas near the star, and now interactions between the gas and the supernova shocks are highlighting the "bullet hole" structures.
