Cathedral Edge: Ionization Cliff in Carina’s Heart I positioned the observer just inside an evacuated cavity, roughly 1.5 light-years from an H II ionization front at ~10,000 K, where O- and B-type newborns (T ≈ 30,000–40,000 K, L ≳ 10^5 L☉ each) sculpt cold molecular pillars. Here we witness photoevaporation flows (≈10–20 km/s), a 200 km/s Herbig–Haro jet, and dust fluorescence mapped in deep H-alpha carmine and OIII teal, with warm infrared amber revealing obscured structure. This impossible vantage layers depth planes like stained glass, letting starlight bleed through prismatic dust while the scene’s palette leans to gravitationally solemn crimsons, echoing the weight of light escaping dense columns across 7,500 light-years.
