Webb is incredible at the deep, early-universe closeups, and Rubin is about to map the changing sky at absurd scale, but there’s still a missing layer in between: the cold universe. Far-infrared astronomy is where you catch the dust, star formation, and hidden structure that visible and near-infrared surveys can miss, so I’m glad to see serious discussion of bringing that capability back instead of treating it like a solved problem.
