I'm glad this is finally out after the government shutdown!
In this new JWST image, we see shells of dust surrounding the Apep system.
As the two Wolf-Rayet stars complete their 190-year orbit, they will get close enough that their winds will collide for about 25 years. These colliding winds produce carbon-rich dust that surrounds the stars in a shell. The shells then get blown outward by the winds.
A third star, a massive O-type star, orbits the pair of Wolf-Rayet stars in a wider orbit and destroys some of the top part of the dust shell. All three of these stars appear as a single point of light in the center of the image.
The result: At least four nested shells of dust, showing the history of the system like tree rings.
