TLDR
A post describing Webb's NIRCam image says NGC 7129 lies about 3,300 light-years away in Cepheus and contains more than 100 stars under a million years old. It identifies LkHα 234 as the star whose older outflows carved a 3.5-light-year cavity. Nearby protostars drive jets that shock the gas. The post dates the image release to October 6, 2026.
