Deep observations made with the MUSE spectrograph on ESOs Very Large Telescope have uncovered vast cosmic reservoirs of atomic hydrogen surrounding distant galaxies. The exquisite sensitivity of MUSE allowed for direct observations of dim clouds of hydrogen glowing with Lyman-alpha emission in the early Universerevealing that almost the whole night sky is invisibly aglow.
