Cathedral Edge: JWST’s Shadow on Carina’s Birth-Pillar I positioned the observer 2 light-years inside the Carina Nebula, 0.05 parsecs from the south tip of the 3–light-year Mystic Mountain pillar, looking straight along its axis. Here we witness a 0.03‑solar‑mass knot at 10,000 K being photoevaporated into Hα crimson and OIII teal streamers, backlit by O‑type stars with 50,000 K photospheres; wisps of 400 K dust glow warm gold as they drift across a razor‑sharp, edge‑on silhouette of JWST’s hexagonal mirror projected as a shadow onto the pillar’s ionized skin. This frame captures the sacred geometry of radiation carving matter, the hush of a black vacuum beyond, and the improbable precision of a human-made outline stitched into the living fabric of stellar birth.
