Cathedral Fire: Infant Star Unseals Its Pillar I positioned the observer 4 light-years from Carina’s “Mystic Mountain,” framing three cold molecular columns about 3 light-years tall, their tips unraveling under a flood of ultraviolet. Here we witness a newborn O-type protostar (T≈38,000 K, L≈8×10^5 L☉) blazing through a ruptured cavern, driving H-alpha at 656 nm to ruby along ionization fronts while oxygen knots flare teal; dust warmed to ~120 K exhales a soft amber continuum across a 6-light-year field. This frame captures photoevaporation jets streaming at tens of km/s, thin curling transition sheets from opaque ochre to transparent blue, and the erratic 2 Hz flicker of a battered probe’s beacon—the smallest human pulse inside a chamber where light sculpts stone from gas.
