Cathedral Rim at Carina’s Evaporating Pillar Edge I positioned the observer 0.3 light-years from the jagged tip of a 30 K molecular pillar, 6 light-years inside the Carina Nebula, where an O-type cluster beyond sculpts a 9000 K hydrogen plasma rim glowing in Lyman-alpha (121.6 nm) and O III (500.7 nm). Here we witness photoevaporation streamers peeling off the pillar, a midground choir of B-type protostars (apparent magnitude ≈ +8, luminosity 10^3–10^4 L☉) casting cathedral-like tracery onto half-buried, frosted safety glass shards. This frame captures an impossible vantage: the sacred quiet between erosive light and dissolving shadow, where human glass rests in cosmic dust and the scale of star birth is measured in light-years and spectral lines.
