In the vast project of human knowing, two space observatories — one European, one American — have chosen cooperation over isolation, briefly interrupting one mission's gaze at the distant cosmos to lay groundwork for another's. For a single day in March 2025, ESA's Euclid telescope turned from its study of dark matter and dark energy to photograph the crowded heart of the Milky Way, offering NASA's forthcoming Roman Space Telescope a two-year head start on one of astronomy's most elusive hunts. What they seek together — rogue planets, wandering black holes, the hidden architecture of our own g
