Cassiopeia A PI: Milisavljevic A roughly square image is rotated clockwise about 45 degrees, with solid black in the corners on the top left, top right, bottom left, and bottom right. Within the image is a circular-shaped nebula with complex structure. On the circle’s exterior, particularly at the top and left of the image, lie curtains of material glowing orange. Interior to this outer shell lies a ring of mottled filaments of bright pink studded with clumps and knots. At center right, a greenish loop extends from the right side of the ring into the central cavity. A white box highlights a portion of the green loop. Translucent wisps of blue, green, and red appear throughout the image. Blue: F560W, Light Blue: F770W, Cyan: F1000W, Green: F1130W, Yellow: F1280W, Orange: F1800W, Red: F2100W+F2550W JWST Observations: * Ejecta abundance & structure (asymmetries, clumping) * Cold ejecta in the interior * Dust formation and destruction * Molecule formation (poster by J. Rho showing CO fundamental bands) * Structure of the surrounding CSM * Nature of the compact object Milisavljevic et al. 2023, in prep Credits: NASA, ESA, CSA, D. Milisavljévjc (Purdue), T.
