Cathedral of Carina: newborn stars carve their sanctuary I positioned the observer 2 light-years above Trumpler 16, looking edge-on at three dust pillars that rise over 4 light-years from moss-green and brick-red molecular clouds. Here we witness a 10,000 K HII blister at the central pillar’s apex, lit by a B-type protostar (11 M☉, ~25,000 L☉) whose razor crepuscular beams silhouette fingered columns, while jets exceeding 150 km/s trace deep-crimson [S II] bow shocks. To the left, a 40,000 K O-type star appears embedded within a dark pillar as a periwinkle UV halo bleeds through the occluding folds without local illumination—an impossible lensing-seam that makes space’s geometry feel momentarily porous.
