The Apep Nebula & Triple Star System | James Webb Space Telescope

The Apep Nebula, also known as the Apep star system, is a triple star system located in the constellation of Norma. It consists of a Wolf-Rayet binary and a hot supergiant star. The nebula is surrounded by a vast complex of stellar wind and cosmic dust. This has formed a "pinwheel" shape by the secondary star's influence. The nebula's appearance resembles a giant serpent, named Apep, in Egyptian mythology. It is often depicted as a serpent devouring its own tail. The Apep nebula is significant in the study of stellar winds and dust formation, as it is a known progenitor of gamma-ray bursts. The nebula's structure and behavior are closely monitored by astronomers to understand the dynamics of massive stars and the processes that lead to their eventual supernova.
Image Processor Judy Schmidt: "Apep is another star system producing a very interestingly shaped nebula around it. These data just came out today, and I spent much of the day processing them. It was certainly challenging, requiring going down to the level 1 data to get the details at the bright center to not be saturated (overexposed)."
"Anyway, the texture seen in the two outer shells reminds me of a sherpa blanket. I don't think there's anything else quite like it. I really wanted that texture to pop, and it was most pronounced on the F1500W data, so I used that for luminosity to give it extra visibility, along with some typical sharpening, clarity, and texture adjustments from the Photoshop camera raw tool. Again, the resolution is not high for this image. Just how it is."
